41.03
HP LaserJet M607–M612: 41.03
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
HP identifies 41.03 as: The job and the paper path disagree about media size; HP documents this especially with self-adhesive media. Do not guess a part yet. The observation that separates the next repair branch is requested job size, tray configured size, actual sheet dimensions and adhesive orientation.
Safety first
Stop and check this first
- Do not print labels with exposed adhesive or unsupported media; adhesive can damage the paper path and fuser.
Safe checks you can perform
- Preserve the failure before clearing it
- Run one controlled, owner-safe discriminator
- Stop at the proved owner/service boundary
Leave these tasks to a qualified professional
- Do not attempt this professional task: Measured service handoff for 41.03
What a technician must be able to justify
A technician is coming
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.
Measured service handoff for 41.03
What they doCompare job ticket, tray configuration and measured sheet length, then test the media-size sensors and registration timing before replacing hardware.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Checks and evidence, step by step
Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
- 1
Preserve the failure before clearing it
No special tools
Procedure
Photograph 41.03 and save the complete event-log suffix, printer model, firmware, tray, media, job and last intervention. A cleared panel is not a diagnosis.
Do not print labels with exposed adhesive or unsupported media; adhesive can damage the paper path and fuser.

Run one controlled, owner-safe discriminator
No special tools
Procedure
Record the job-requested size, tray-configured size and actual sheet dimensions. Reload supported media in the documented orientation and retest one sheet. Record requested job size, tray configured size, actual sheet dimensions and adhesive orientation; change only one variable before the retest.
Do not print labels with exposed adhesive or unsupported media; adhesive can damage the paper path and fuser.

Stop at the proved owner/service boundary
No special tools
Procedure
If all three sizes agree and 41.03 repeats, the media sensor/registration branch needs service; if they differ, correct only the mismatched layer.
Do not print labels with exposed adhesive or unsupported media; adhesive can damage the paper path and fuser.
