HP LaserJet Enterprise M506 MICR issues

Tim_Feazelle · ‎01-09-2020

My company uses our HP LaserJet Enterprise M506 for small batch check and invoice printing. For checks we have to use MICR toner. For invoices we use standard toner.

Whenever we print with the MICR toner then switch back to standard, all the pages come out blank until we take the standard toner out and put it back in. It happens every time and as soon as we reseat the standard toner it prints fine until we have to swap to MICR then back again.

We use genuine HP toner for our standard toner, but to my knowledge HP doesn't offer MICR toner, so we have to go to a third party. We have tried different MICR distributors thinking that maybe it was a fault with the MICR. We get the same results.

Has anyone else experienced this or have a fix for this situation?

Do you power off the printer before changing cartridges?

No. But I have tried power cycling the printer after it fails to print correctly, multiple times. Never has it corrected the problem. The only thing we have found that works is to remove the HP standard toner cartridge and then reseat it.
