Why does the printer print horizontally and not vertically

Citizen CLP-621. Repair, calibration, adjustment

One of the most reliable printers on the market for label printers, it has one very unpleasant property, mechanics who very rarely meet Citizen CLP521 / 621 in repair (by the way, LABEL PRINTER JM20-M01 is written on the nameplate of this printer), they know little about these printers, and even this a simple operation, like a diagnosis, baffles mechanics. The printer is made according to such a classic scheme that one can only wonder why, for example, a simple calibration operation raises so many questions.

It is worth paying attention to the fact that the CLP 6xx series printer supports two types of printheads. 203dpi and 300dpi. While the CLP 5xx is only 203dpi

Let’s consider the calibration operation from the perspective of a beginner who sees the Citizen CLP521 / 621 label printer for the first time. The text written in italics is intended for the category of people who see the label printer for the first time.

Calibration is required if, when printing a single label, a label and one or more blank labels come out, or when printing a large number of labels, blank labels are encountered.

Before proceeding with the diagnostics, it is necessary to check the correct positioning of the sensors one above the other, depending on the selected type of sensors. Then we try to calibrate the sensors to the paper / label. If the calibration does not help, then it is recommended to reset to default settings, switch to direct thermal mode and set the sensors to the light. Perform calibration in this state, if the calibration fails, then with a 90% probability the sensors are faulty.

All Citizen CLP521 / 621 printer repairs are mechanical repairs. These are malfunctions of the thermal print head (TPG), shaft, (example of wear of the Citizen CLP621 printer shaft), sensors.

Approximate life data of parts

Sensors. 250-350 km (cleaning of the transparent plastic covering the sensors, every 100 km is necessary)

Shaft rubber under the head in TPU for the printer SHK Citizen CLP-621.150 rubles.

Lower label sensor for Citizen CLP621 1400 rub.

Removing the bottom sensor is fairly straightforward if you approach the process from the right side. The difficulty lies in the fact that it is quite difficult to get to the fastening bolt, you can twist the bolt with the edge of a slotted screwdriver, while the screwdriver is located at an angle to the bolt being loosened.

Shaft has a tendency to wear, an example of a Citizen CLP621 printer shaft wear. Removing the shaft is quite simple, but if you remove the shaft too vigorously, there is a chance of breaking the fastening latch.

Calibrated to media. Continuous tape (label).

Turn on with the three upper keys pressed (Pause, Feed, Stop), after the three upper LEDs light up Power (Green), Print (Green), Condition (Orange), the printer will beep, release the keys.

Then press the Mode / Repeat key and without releasing the key press Pause, the chip comes out at a very slow speed, while Power (Green) is on and Condition (Orange) blinks. When the top LEDs light up (Power, Print, Condition) the calibration is almost complete. We exit the setup mode, press the Stop key, all the LEDs briefly light up and then go out, while the printer emits one sound signal, only the two upper LEDs Power (Green), Print (Green) remain on. Calibration is complete, it remains only to check the results, for this we press the Feed button, one label should come out.

Note. When the Feed button is pressed for the first time, two labels will come out, this is normal, with subsequent presses one label will come out, if the calibration was carried out on continuous paper, then the first time you press a piece of paper of double length, no more than 5-10 cm.

Note. If, when trying to calibrate, you get an error “No mark or gap between labels”, then try loading the paper so that the end of the label is as close as possible to the sensor, for reliability, remove the next label from the backing.

Description of indicators.

Power indicator Lights up green when the power is turned on.

Print light turns green when the printer is ready to print.

Condition Indicator Lights up orange when setting mode is selected.

Error indicator lights up in red when an error occurs.

Printer errors. Error table.

Switching the print mode. Direct Thermal / Thermal Transfer.

Citizen CLP621 printer supports two printing modes.

Direct thermal

Thermal transfer (ribbon) printing. Thermal transfer

From ready mode, Power (Green), Print (Green) is on, press the Mode / Repeat key and without releasing the key, press the Pause key, the print mode will switch, you can determine the received mode by the light and sound indication.

Direct thermal. the Condition LED will blink twice and the printer will beep twice.

Thermal transfer printing. the Condition LED will blink and the printer will beep once.

Attention! Technically, switching the print mode means not only turning on and off the ribbon take-up mechanism. This is also the inclusion of a sensor located on the reference disc, which in turn is located on the driven shaft. Thus, the absence of a signal from the sensor of the driven shaft means that there is no ink ribbon, which means that the printer is blocked. An important conclusion. Termal Transfer operation is not possible without ink ribbon!

Entering the sensor adjustment mode. Transmission sensor / Reflection sensor.

Press the Pause, Feed, Stop buttons at the same time while powering on the printer.
When the Condition indicator (Orange) is on, release the buttons to enter the sensor settings mode.

To switch from Reflective to Transparent, be sure the Condition LED (Orange) is on. While holding the Mode / Repeat button and press the Stop button, you toggle between the two types of sensors.

  • If See Through is selected, the Print LED (Green) will light up and the buzzer will sound once.
  • If Reflect is selected, the Print LED (Green) flashes and the beep sounds twice.
Attention! Transmissive sensor detects gaps between labels and reflective sensor detects black marks.
Attention! Only one sensor can work at a time, either against the light of Fig. 7, item 2, or against the reflection of Fig. 7, item 1

Attention! There are two types of transmissive and reflective label sensors. In one embodiment, the sensor emitters are always on, in another version the sensor emitters are switched on only at the time of printing.

Mechanical Installation of Label Sensors.

For proper operation of the end-of-label sensors, the sensors must be correctly positioned relative to each other. It is quite simple, it is enough to carefully consider explaining the installation of the sensors. Installation of sensors, for the operation of different types of sensors is somewhat different.

Advice. To simplify the installation of sensors in the light, there is a locating tab on the movable paper width limiter.

Set the paper width limiter (Movable media guide fig. 8) to the required paper width.

Move the upper sensor (Upper Sensor Fig. 8) and the lower sensor (Bottom Sensor Fig. 8) as close as possible to the paper stopper. Then, with the paper stopper, move both sensors approximately half the width of the paper. Thanks to the locating lug, the sensors are ideally positioned relative to each other.

We return the paper width limiter (Movable media guide Fig. 8) to the required paper width.

Resetting the Printer to Default Settings.

We fill paper with a width of at least 80mm. Turn on the printer by holding down the Mode / Repeat key, the printer issues a receipt with a printout of the recommended actions.

To reset the settings, press the Pause key, the printer issues a receipt with recommended further actions,

respectively, press the Feed button and hold the button for at least 3 seconds. The printer issues a new ticket, with further recommended actions that allow you to print a list of the settings obtained as a result of the reset.

Electrical voltage measurements from sensor connectors.

Voltage measurements at the sensor connectors. Connectors for the upper and lower sensors located under the case, and two pull-up resistors located under the small cover of the printer.

Probably an exotic necessity. But sometimes it is necessary to short-circuit the TPG opening sensor, for example, to check the operation of the paper sensors on the firmware of a new sample.

How to disable TPG thermal sensor.

The thermistor has a resistance of 22kΩ at room temperature. On the loop, the terminals of the tremoresistor 9 and 10, starts with a red wire.

Setting system options

The CLP 621 printer comes with a wonderful utility for setting system options from a computer, a very convenient utility is highly recommended for use.

There are two ways to switch the side of the working layer of the thermal transfer tape. From the printer keyboard or a switch on the thermal transfer ribbon drive mechanism.

The default winding is IN.
To switch to OUT:
– turn on the printer
– with the printer turned on, press and hold the MODE / REPEAT and PAUSE buttons for 4 seconds
– a triple beep will sound. printer in OUT mode
– when repeating the procedure, the beep will sound 4 times. printer in IN mode

Chip locks and ink sensor disable for HP 711, 950, 951, 933, 932 cartridges on HP T120, T520, T125, T520, T530, 8100, 8600, 8610, 8620, 8630, 251dw, 276dw, 8640, 8650, 8660 printers. 6700, 6100, 6600, 7110, 7610, 7510, 7612

Chips are vulnerable in original HP 711, 950, 951, 933, 932 ink cartridges, compatible ink cartridges (for example, for 950/951 or 932/933 ink cartridges) and similar ink systems for HP.

The fact is that on the printers HP T120, T520, T125, T520, T530, 8100, 8600, 8610, 8620, 8630, 251dw, 276dw, 8640, 8650, 8660, 6700, 6100, 6600, 7110, 7610, 7512, 7612, 7510 dual ink control:

  • By the counter of the ink consumption in the chips (the printer calculates when the ink runs out and writes the data to the chip). After the end of this counter, you can use the cartridges and then by clicking OK in the warning window that appears. this will “turn off” the chip (more precisely, it will turn off warnings and allow you to print further).
  • By the sensor of the actual presence of ink in the print head (if there is no ink by this sensor, the message “it is necessary to replace empty / used cartridges” appears). over, the sensor works in two ways: 1) it simply detects the presence of liquid on the contacts inside the steam generator (in this article, we are talking about turning off this sensor), 2) it records the pressure of the pump and electronically. the permeability of the nozzles in the print head (it cannot be turned off in any way. in any case it will give an error in case of problems with the paint supply).

If you insert empty cartridges, skip refueling or use low-quality ink, a repeated error of the ink sensor can block or damage the chips, so carefully monitor the status of the shut-off valve and CISS. We recommend that you completely block the ink availability sensor when switching to alternative consumables so that the chips serve as long as possible.

It should be borne in mind that the printer remembers on which chips this error appeared, therefore, after reinstalling the cartridges, the error repeats. At the same time, the blocking of the chips can be reset if you insert and allow other shut-off valves with serviceable chips or filled originals to be identified (and it is easy to fill them). Then insert the previously locked cartridges. But the design of the print head is such that the printer very rarely, without outside intervention, can re-fill the compartments where these sensors are installed, therefore, most likely, this error will be repeated soon.

The ink sensor is disabled by closing the contacts on the SG using a soldering iron or wiring. One “but”: if you miss refilling cartridges, the printer may not see the actual lack of ink, and due to the thermal inkjet printing system, it may damage the print head (without ink, the heating elements in the head nozzles overheat). Steps below.

  • Remove the cartridges from the printer.
  • Remove the print head (you need to move the lever on the right of the carriage on T120, T520, T125, T520, T530, 8100, 8600, 8610, 8620, 8630, 251dw, 276dw, 8640, 8650, 8660, on 6700, 6100, 6600, 7110, 7610. 7510, 7612 the head is removed with the disassembly of the entire body).
  • Unscrew the two screws at the back that hold the electronic board.
  • Close two contacts each (as in the photo). This can be done with or without a soldering iron by placing small pieces of wires (or double-folded unpainted staples) on the springs and pressing them down with a board. In general, these contacts are closed with ink in the buffer ink chamber in the head: when the ink runs out, there is no short circuit and the printer gives an error, although sometimes the sensor is triggered by mistake due to air or shaking. After this procedure, the printer will not respond to this interference.

Shorting the HP 8100/8600 Printhead Pump Sensor Using Wiring

In case of problems with ink supply, the printer can still report errors, but the probability of blocking chips is reduced (for example, an error is possible. “ink sensor signal”. is eliminated by clicking “OK”).

Using “Text” to write vertically

The second way is to insert a “decal” that can be rotated. You need to go to the “Insert” tab, and there you will already find “Inscription”.

We select a “simple inscription” there. We will have a square with standard text inside. We delete it simply by clicking on it to select it and pressing the “delete” key. We write our own. The example says “Vertical Text”

Then double click on the frame. You will notice that the menu at the top has changed. there will be new tools for working with labels.

By clicking on the “text direction”, it will rotate vertically.

In the “Shape Outline” section, you can select “None”, thereby removing the frame around the text.

Three ways to write text vertically in a Word

We will look at three ways that allow you to write vertical text in a Word. Many sites advise you to create a table, and place the rotated text in it.

We will talk about this too, but the method without using tables will also be described. So let’s get started.

Vertical (rotated) text using a table

Select one cell for the table. Enter the text you want into it. Right click and select Text Direction.

Choose the one you like. In the screenshot, the text direction is from bottom to top.

We can expand the table cell by pulling the bottom line and narrow it by pulling the right line.

Thus, we will rotate the text in the Word vertically.

To make the borders of the table invisible, right-click on it and select “Borders and Fill”

And on the tab with the “Border Type” boldly choose “No” and press OK.

This results in a clean vertical line:

We write in a Word vertically in a column

There is also a third option for those who do not need an inverted text, but need it to be written in a columnar manner.

The first thing you need to do is write one letter at a time and press “Enter”, that is. write each letter from a new line.
Second. select the column and select “Line spacing” in the top menu of the Word, and there “Other line spacing options”.

And manually enter a value, for example, a multiplier of 0.7 to shorten the distance between the lines

That’s all. Good luck with learning Microsoft Word.
