Printer won't print, says it does not recognise the cartridges. it flashes 1 then a C then an e. HELP.nd a C

The problem could be due to a communication failure between one of the printheads (cartridges) and the All-In One (AIO) or by a short in one if the printheads. Please follow the steps below to identify and fix cartridge issues:

  1. Make sure the printer is on.
  2. Open the printer cover. The print cartridge carrier moves and stops at the loading position, unless the All-In-One is busy. Note: If the carrier does not automatically move to the center, turn off the printer or unplug the printer from the power source and then carefully slide the carrier to the center.
  3. Remove both cartridges from the carrier.
  4. Close the printer cover.
  5. Re-brick your printer by pulling out the power supply - black box behind the printer where the power cord is plugged in to, and re-plug after 30 seconds.
  6. When the printer turns on, reinsert one cartridge first. Close the printer cover and check for any errors.
  7. If no error appears, reinsert the other cartridge. Close the printer cover.
  8. Replace whichever cartridge is causing the error to appear with a new genuine Lexmark cartridge. Try to print a document again to verify that the problem is fixed.

Epson workforce 520 won't recognise ink cartidges

When replacing ink on the Epson Workforce 520, Ensure the cartridges have the correct/same number of gold contacts. Ive seen them with 7 and 9 gold square contacts and they were otherwise identical, and the ones with 9 contacts threw an "cartridge not recognized" error on the printer's dispay.

HP Print cartridges are unrecognised


I understand your concern, the cause for this problem is you are trying to install the cartidges which belongs to different zone. This is due to regionalization of the cartridges. As you have bought the printer from UK you should get the cartridges from that zone only.

Click here to know which zone UK belongs and which cartridge is compatible with your printer. From the link you can find UK belongs to zone 2 and New zealand belongs to zone 1. So return the uncompatible cartridges and replace it with zone 2 cartridges.

HP 4280 - new black refilled cartridge not recognised

hi steve... the solution to your problem is a costly one. the printer keeps in memory 2 cartidges for colour and 2 for black, when a third is placed in the printer the first one is deleted out of memory same for the colouredand same for the black... therefore you need 3 cartridges each to do the trick.
eg. if you want to use colour cartridge #2 then 1st place colour nuber 1 or 3, then turn it on let it reads, then open door and place in colour number 3 or 1 let it read, then take out and place in coulur number 2 and it will see it as new

Printer cannot recognize ink cartridge

Check the PG 40 & 41 Labels are near the top lugs and not near the curved lug and make certain that the cartridges are fitting in right. If the label has slipped down the 'chip' can not be read and error message will come up.

Compatibility of Ink cartidge.

The MP600 does not use the 40 or 41 cartridges, it uses individual color (and black) ink tanks. But other models (MP190, MP460, MP470, etc) do use these cartridges. The error message you are receiving indicates that the printer does not recognize the cartridge you installed as a valid black ink cartridge. This can mean that either the cartridge is faulty, or that the printer has a problem.
I would suggest trying another new cartridge, and if you still get the same error, to contact Canon for support options if the unit is still in warranty.

Lexmark x1180 printer all in one

Clean the contacts on the cartidge and printer ( open the replace ink door wait for the printhead to come to center and turn off power) if that does not work then replace cartridge, it might be a recycled one that they did not chane the chip.

Cartidge problem

Many "compatible" cartridges are badly manufactured or even labeld wrong. These can damage or block the connectors on Epson printers. your best bet is go buy new ink and try them, then if it still dont recognise, you could buy some ink cleaning cartiridges and give them a try - Google "Epson Print Head cleaning" Failing that go buy a new printer - Epson's are real cheap new.
