Within the last month, I get this "Paper is too small" error when I try to print 11" by 17" or above. HP support tells me that the problem is faulty paper sensors in the printer. There is nothing they can do except offer to sell me a new printer (mine is past warranty). Does anyone have a solution other than scraping the printer? Is there a way to override the sensors?
This model uses the sensor under the carriage to detect and size the paper. It cannot operate or check the dimensions of the page without this sensor operating.
You may be able to clean the sensor, though I've done that on one of these printers with the same problem without success. Make sure that the carriage path is smooth, as dry rails and unnecessary vibrations can upset the sensor readings, especially when the bushes get a little worn and the carriage starts to wobble more than usual.
Also check the connections from the sensor to the logic board, remove and reinstall them as this may clean the contacts. I often give them a wipe with alcohol. Sometimes the sensors used are commercially available from vendors like Farnell and you can replace these, but, more often than I like, they use specially developed units. I haven't had to look for the unit for this model in the past. Though I am looking at one of these beasts with this exactly the same problem tomorrow and I may have to follow what I have typed in this reply. If I have to replace the sensor, then I will let you know if I find a commercial equivalent.
Since the unit I am going to look at, detects some sheets okay and rejects a lot of them, I am beginning to think it is not the sensor itself, but the connecting cable to the sensor. Because the carriage cable is constantly waving back and forward, sometimes the metal fatigue in the cable will form cracks or breaks that open and close during movement, giving intermittent poor readings but also good readings when the cracks are closed. So I will be testing this as well.
If the above fails, I will have to let the school who owns this printer an offer of a replacement as HP would do to yourself. Sometimes this is the easiest path to take.

The sheet feed detector is bent out of true, which would start the error message, after checking that it touched the paper, see if the feed rollers are misaligned, or, are damaged. If there is a cog tooth drivebelt on this, see if the belt has snapped or is off the cog. After that, it could be a faulty sensor switch
Have/had the same problem: Getting "paper size mismatch" on the C4280 status
screen, after we got a paper jam. Every time we hit OK and put in paper,

The problem is the paper size sensors. Remove the plastic access panel that
is for access to the rollers in the back and has 4 rollers on it. There are two
papaer sensors attached to the printer circuit board (PCB). The control arm for
the sensor is a small plastic piece that extends slightly into the paper path
above the PCB. The plastic can be broken when you are removing a paper jam. I
stuck a small piece of a match stick in the sensor to keep it open (as though a
wider piece of paper was passing throught the printer). I can't switch to
smaller card stock, etc, but who cares, it works.
The copying problem is caused because the C4280 will not scan correctly until
after it does the alignment phase.
41.3 - points to a miss match in the paper tray. First - Pull out your paper trays, take the paper out and confirm the guide in the back is set to the correct position. (The little mechanism on the tray which allows you to use different paper types, example letter to A4).
Second - The other which may have happened it the paper handling was mis-configured on the machine: - Press the Menu Button on the machine. - Using the + and - button go to the Printing Menu. - Select Paper confirm that the paper size is correct for the trays within the machine. Third - - Depending on the document you are attempting to print make sure the document type is either adjusted to the type of paper your using or to load the correct paper into the machine. I seen where people send you a legal document and your attempting to print it on letter. Fourth - It could be a driver related issue, 98% of the time this is not the case. If all fails above, then attempt this. Let me know if this helps! Lastly it could be a driver related issue, however if more than 1 person uses it don't count on it.

Problem Solve. Same error. Generally either a real or phanton jam from the paper tray or manual feed tray.
SOMETIMES the manual feed would work but always one corner on the paper turned down when printed.
Remove toner cartridges and bottom paper tray
Turn printer on its back. The black plastic flap (about 9" long) that hangs down a small amount (near the white main feed roller) had one end most likely the wrong side of the small metal rollers above it.
This flap should hang about vertical. One end of it is most likely the wrong side of the small mostly metal roller above it. Each End of this flap should be about mid way between the two smaller metal rollers.
WITH CARE take a timber skewer and carefully encourage this flap back so that both ends are in the correct place
HP is a terrific printer. Try cancelling the print request in the computer, turning off the computer,then unplugging the printer, giving them a few minutes to re-set, then, then turn them on again. Also, look for a small, torn piece of paper within the printer, in case it is causing the issue. Best of luck.
Hello Julie how are you? Regarding on your problem try to remove your cartridge then installed it properly. Or try to open the back of you printer and try to see if their is a small piece of paper left during a paper jam incedent you have.
This could be a mis-match of paper sizes. Example, computer could be sending an A4 page to the printer. The paper size in the could be set to Letter. Ensure the 4 paper sizes match, in the computer - the document and printer driver; in the printer (change in control panel) and paper tray (adjust the physical side and length).
