How to fix the Canon ‘Check Ink’ U075 or U076 Error Message

How to fix the Canon ‘Check Ink’ U075 or U076 Error Message

Your Canon inkjet printer gives ‘Check Ink’ error messages when it has detected a problem with at least one of the installed cartridges. The nature of the issue however is indicated by the code that follows. Canons official description for the U075 or U076 code is that a “FINE Cartridge is not installed in the correct position”. Although the message refers to the ‘FINE’ branding on a cartridge (which only usually appears on the packaging of Canon original cartridges), you can use any compatible remanufactured or refilled cartridge in this range of printers. A ‘FINE’ cartridge is any Canon cartridge that has a mechanical printhead included within the cartridge like those highlighted in the image below. Canon Fine Printhead

Why am I receiving this error message?

The good news is, if you are receiving the U075 or U076 code your printer is capable of reading the cartridge but has just detected it is in the wrong side. Although the colour and black cartridges look very similar and the two cartridge positions within the printer are nearly identical, the cartridges must be installed it a set position for your printer to be able to recognise them. Unfortunately you cannot install two black cartridges even if you are only planning on printing in black and white.
If you open the lid of your printer you should notice some indicators on the cartridge cradle or the body of the printer that show which side each of the cartridges should go.

In most printers the tri-colour cartridge will need to go in the left hand position and the black cartridge in the right (as shown above).

How do I clear the U075 or U076 error?

Most people will experience immediately after changing an ink cartridge due to misleading branding either on the new cartridge or the one they have just taken out. Resolving the issue is a simple matter of making sure one of each (black and colour) cartridge is in the printer and in the right position.Please take the following steps:

  1. Open the lid of the printer and wait for the cradle to move to the cartridge replacement position.
  2. Remove both cartridges from the printer.
  3. Examine the labels to ensure one is a black (PG-37/PG-40/PG-50/PG-510/PG-512/PG-540/PG-540XL) and one is colour (CL-38/CL-41/CL-51/CL-511/CL-513/CL-541/CL-541XL).
  4. Locate the correct slot for the colour and the black cartridge using indications on the printer or cartridge cradle.
  5. Re-install both cartridges into the correct slot.

The message will now disappear leaving you to continue printing. If however the message remains it may be that one or more of the cartridges has been miss-labelled by the manufacturer. To confirm if the cartridge is colour or black  simply turn them over and examine the printhead on the underside of the cartridge. The colour cartridge will have three separate slits in the central metallic square and the black will have a single elongated slot as demonstrated below.


What printers does this advice relate to?

The U075 or U076 error codes  appear on a wide variety of Canon inkjet printers that take the Canon PG-37, CL-38, PG-40, CL-41, PG-50 and CL51 ink cartridges. These printers include the Canon Fax JX200, MultiPass 450, MultiPass MP150, MultiPass MP160, MultiPass MP170, Pixma iP1200, Pixma iP1300, Pixma iP1600, Pixma iP1700, Pixma iP1800, Pixma iP1900, Pixma iP2200, Pixma iP2400, Pixma iP2500, Pixma iP2600, Pixma MP140, Pixma MP150, Pixma MP160, Pixma MP170, Pixma MP180, Pixma MP190, Pixma MP210, Pixma MP220, Pixma MP450, Pixma MP460, Pixma MP470, Pixma MX300 and Pixma MX310.
