Check the grounding wire and connectors. tighten all screws. If issue persists, call Citizen service center.
This error message refers to Check memory error...This error Occurs if a Memory read after write or FROM sum check has resulted in an error.(Unrecoverable error)
Its a very common problem this occurs when a high voltage pass through the board plz if u r still under warrantly act soon as u can if u r not i recommend u that dont even try to change the borad cuz itd cost u the a new printer!!
plz rate this poste

Turn it off and disconnect interface (parallel/serial/usb/ethernet) cable from host and also disconnect power cable and leave it for 3 mins.
Reconnect the power cable only and with the thermal paper loaded properly, PRESS and HOLD the Paper Feed button WHILE turning the printer ON. Release only after it starts printing.
No change ? Remove power cable again and re-seat the interface card (located at the back with two screws on each side) and try the above maneuver again. (PRESS and HOLD the Paper Feed button WHILE turning the printer ON. Release only after it starts printing.)
Still no change ? At this point the Thermal Printer needs service. Contact manufacturer for service options.
Also try going into control panel click on printer and go into printer maintenance I have sometimes been able to get printers to respond by tweeking some of the property adjustments. I also have a printer that freezes and the light will blink in tandem. The owners manual has owner hold the lower button on my printer and that will usually rest and then hit reprint. Hope this helps.
Pull your cartidge then refix agai .
chaeck in both sede that there is not any paper jam.
also try to change the cartidge if problem not resolved.
Hello Colin843,
First unplug your printer fora couple of minutes.
If you still have the problem, make sure your connection between your printer and your computer is okay.
If it is, reintsal (or instal if you havent done it) the driver of your printer on you computer.
If the problem persist, lem me know,
Good luck,
Dahaka
Try first to unplug the power of the printer for 5 minutes and then after that check again the lights and see if you can now the printer....
Remove the power cord for sometime then reinsert.it may get resetted.
if does not solves your problem by that open the front cover.remove all the papers inserted.and look any thing like paper piese is blocking the cable to move.or any internal cable loose.if loose cable the printer has to be opened and the cable should be fitted properly.
thanks
if the inter nal board is faulty or short circuit has happened due to extra voltage passed .then replacing the board will cost u near to new.
also check out that if the board has any problem
thanks.

1 POWER lamp (Green)
Lights when the power is turned on. It blinks when
a memory check error has occurred.
2 ERROR lamp (Red)
Lights or blinks to show different error states. It
also blinks while the printer is waiting for a macro

Pressing this switch briefly causes one line of
paper feeding.
While a macro is waiting to be executed, pressing
the switch causes the macro to be executed.

Description of errors
Memory Check error:
This error occurs if a memory read-after-write check or FROM sum check has resulted in an error
(unrecoverable error).
Cover open:
When you open the printer cover, the cover open sensor is activated, causing the ERROR lamp to
light and the printing operation to stop. (Not recoverable error)
Head overheat:
To protect the print head from overheating, the head temperature sensor is activated if the head
temperature rises over approx. 65°C, causing the ERROR lamp to blink and the printing operation to
stop. Printing resumes automatically when the head temperature lowers below approx. 60°C. (Auto
recoverable error)
Paper near-end:
As the paper roll diameter becomes small, the Paper near-end sensor is activated and causes the
ERROR lamp to light, indicating the paper supply has become low. (See “Selecting the paper sensor
valid for paper end signal output” and “Selecting the Paper Near-End Sensor valid for print stop”.)
Paper end:
When the paper roll has run out, the Paper end-sensor located near the print head on the paper
path detects the end of the paper roll, causing the ERROR lamp to light and printing to stop. (See
“Selecting the paper sensor valid for paper end signal output” and “Selecting the Paper Near-End
Sensor valid for print stop”.)
Cutter motor lock:
While the cutter motor is running, if the cutter position detecting sensor inside the cutter unit
remains ON or OFF for approx. 1 second or more, the printer determines that the motor has locked,
causing the cutter operation and printing to stop. (See “Removing Jammed Paper”.)
Low voltage error:
Occurs when the voltage supplied to the printer decreases ; if this has occurred, turn the power off
immediately. (Not recoverable error)
High voltage error:
Occurs when the voltage supplied to the printer increases ; if this has occurred, turn the power off
immediately. (Not recoverable error)
Waiting for label cutter action:
Wait until the label discharged by the GS+FF (Cut Label and Discharge) command is cut by the
manual cutter and the FEED switch is pressed. If “No Cutter” or “No Peeling Mechanism” is
selected, the printer becomes Busy.
Waiting for Label Discharge:
Waiting for a label to be removed from the base sheet after it was discharged by the GS+FF (Cut
Label & Eject) command (if the peeler is selected). The printer becomes Busy.
Label detection error:
Label gaps or black marks could not be detected, or the label sheets used do not fall in the specified
length limits.
If a label detection error occurs even though the label sheets used fall in the specified length limits,
it is most likely that the sensor or its peripheral electronics is defective. The printer becomes Busy.

Tried another power unit, no luck
I have tried a new power unit. No change.
Need more help
Printer not connected to computer, it is a printer fault
Receipt printers do not have cartridges. Paper roll not jammed.
Printer not connected to computer, it is a printer fault. I need someone to diagnose the fault codes for this blinking.
No luck still. I need someone to diagnose the fault codes for this blinking.
The manual only covers for one blinking, not two, I guess it is U/S thanks guys
Did not solve the problem but did prove that it is a major problem
