- 10.100X Supply Memory Error
- 10-100x
What usually causes it
- The indicated cartridge is not fully seated, so the printer cannot communicate with its memory chip.
- The cartridge's memory chip is damaged, contaminated, or defective.
- A cartridge intended for another product or an incompatible remanufactured supply does not provide the expected memory information.
What to try
Use the X position to identify the affected cartridge
Record the full 10.100X message before moving supplies so you know which color/location the printer originally reported.
Remove and reinstall that cartridge
Power down if the product guidance requires it, then seat the indicated cartridge firmly in its correct slot without touching or scraping the memory contacts.
Inspect the cartridge for obvious damage or incompatibility
Confirm it is the correct supply for the M375/M475 family and that the memory-chip area is intact.
Try a known-good correct cartridge if available
If the error follows one cartridge, replace that supply. If multiple known-good cartridges fail in the same slot, preserve that evidence for service.
After each corrective action
Retry the same operation that produced 10.100X Supply Memory Error. If it now works, stop there rather than changing unrelated printer, network, supply, or service settings.
If the code returns
If 10.100X returns with a known-good correct cartridge, record the exact X value and which slot is affected before contacting HP support; repeated failure in one slot can indicate a printer-side contact or electronics problem.
When service may be needed
User-safe work should stop at reseating or replacing the correct cartridge. Do not bypass supply contacts or open the printer's electronics; persistent memory communication faults may need HP service.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
