Canon 2900 on an inkjet printer: alignment sheet scan failed
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
The printer could not scan the print head alignment sheet. Press OK, place the sheet on the platen in the correct position and orientation, make sure glass and sheet are clean, and run auto alignment again on A4 or Letter plain paper.
Safety first
Stop and check this first
- Do not use photo paper or sizes other than A4 or Letter for alignment: Canon expects plain paper in the rear tray.
Safe checks you can perform
- Alignment sheet position
- Clean platen and sheet
- Nozzle check pattern

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Platen scan check
What they doIf alignment fails with a clean, correctly placed sheet and a complete nozzle pattern, the Canon service technician checks scanner reading with a scan test and a repeat alignment.
They must show youa scan test and the repeated alignment with its result.
In writingwhat was tested, which part was replaced if any, and why.
Print head check after cleaning
What they doIf the nozzle pattern still has gaps after the printer's own cleaning routines, Canon service checks the head or cartridge before proposing replacements.
They must show youthe nozzle pattern before and after their work.
In writingthe diagnosis, the reference of anything replaced and the date.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Alignment sheet position
- Who:
- you, no tools.
- How:
- press OK, open the document cover and place the printed sheet on the platen in the position and orientation shown by the alignment mark. Close the cover slowly and start auto alignment again.
- Result that matters:
- the printer reads the sheet and finishes alignment.
- If it finishes without an error:
- placement was the cause.
- If 2900 returns:
- go on to cleaning the platen and the sheet.
- Evidence to keep:
- photo of the sheet on the platen.

Clean platen and sheet
- Who:
- you, with a soft dry cloth.
- How:
- check that the platen glass and the alignment sheet have no marks, dust or fingerprints; if the sheet is creased or marked, print a new one on A4 or Letter plain paper loaded in the rear tray.
- Result that matters:
- a clean, flat sheet on clean glass.
- If alignment works after cleaning:
- dirt was the cause.
- If it still fails with everything clean:
- print the nozzle check pattern.
- Evidence to keep:
- note of what you cleaned and whether you used a new sheet.

Nozzle check pattern
- Who:
- you, from the printer panel or software.
- How:
- print the nozzle check pattern and look for missing lines or blank colours. If the pattern is complete and 2900 stays, cancel with OK, load A4 plain paper in the rear tray and try the manual alignment Canon describes.
- Result that matters:
- a complete pattern with no gaps.
- If lines are missing:
- clogged nozzles explain the scan failure; deal with that before aligning.
- If the pattern is complete and manual alignment also fails:
- ask Canon service to check it.
- Evidence to keep:
- photo of the nozzle check pattern and the alignment sheet.

What it means
In the PIXMA TS3300 manual, Canon defines support code 2900 as a failure to scan the print head alignment sheet. Auto alignment prints a pattern and then reads it with the platen scanner; if the sheet is misplaced or dirty, printed on the wrong paper, or the pattern is incomplete because nozzles are clogged, the scan fails. That is why the code does not point to a part: placement, dirt, paper and nozzles come first. Check your own series list to confirm the code means the same.

Symptoms and causes
Probable causes · in order
- Sheet misplaced on the platenCommon
Canon asks you to check the position and orientation of the sheet. This fits if alignment completes once the sheet is placed printed side down against the mark.
Evidence: Canon PIXMA TS3300 support code 2900
- Dirty platen or sheetPossible
Marks or dust on the glass or the sheet stop the pattern being read. You can tell because the error clears after cleaning both and nothing else.
Evidence: Canon PIXMA TS3300 support code 2900
- Incomplete pattern from clogged nozzlesPossible
If the nozzle check pattern has missing lines, the scanner cannot measure alignment. Printing that pattern confirms it.
Evidence: Canon PIXMA TS3300 support code 2900
- Wrong paper for alignmentPossible
Canon asks for A4 or Letter plain paper in the rear tray for alignment. Photo paper or another size gives a pattern that cannot be used.
