41.03.A2 ERROR HP LASERJET M607 M608 M609 PRINTER: UNEXPECTED SIZE IN TRAY 2 RESOLUTION

Updated: Jul 12, 2023

How To Solve 41.03.A2 Errors Load Tray 2: Plain , A5


The “Size Mismatch in Tray 2” error is a common error code on the HP LaserJet M607, M608 and M609 products. This typically means that the Paper Size Detection Switch Assembly (RM2-1255) is defective. This error is often associated with the 41.03.A2 error.

We have found that this issue occurs when tray 2 is loaded with a full ream of paper.

The printer will, at times, revert to a “Load Tray 2: Plain, A5” message on the panel and broadcast a message that the device detected an unexpected paper size. Sometimes, when removing approximately 300 or more sheets of the paper from the tray and re-inserting the tray will bring the printer to read “Tray 2 Letter” message or similar.

The error returns when a larger stack of media is placed back into the tray. The display will come back and indicate that the correct media is loaded with no errors.

We’ve also noticed that when the tray is gently inserted into the printer with a full ream of paper, it will not recreate the error. We’ve attempted this with the replacement of the switch and without it. In most cases, the error does not occur. This error also seems to occur on the touch screen units.


The removal of the switch can be a bit daunting with the removal of the left side lower cover and the DC Controller. The cable guide assembly will also need to be removed out of the way, there are two tabs securing the assembly behind the printer frame.

Once the cable guide assembly is removed, the access to the screw securing the switch cover assembly can be obtained. Prior to reinstalling the new switch assembly, it is recommended to extend the spring on the cover to allow for more tension on the switch arms. This can assist in eliminating future paper size errors.
