HP 10.x — Supply memory error

What this error means

The printer can't read the memory chip on a toner cartridge — a poorly seated cartridge, a dirty chip contact, or (frequently) a compatible/refilled cartridge with a bad chip.

Symptoms

• Error right after replacing toner
• Supplies status shows a cartridge as missing/unknown

Try this first (safe DIY steps)

1. Remove the cartridge, check the chip contact for tape or debris, reinstall firmly
2. Try a different cartridge — if a compatible brand fails, an OEM cartridge is the decisive test
3. Power cycle

Safety: power off before any physical intervention. Never bypass covers or interlocks — fuser areas run hot enough to burn.

When to call a technician

Rarely needed — if OEM cartridges also fail, the contact assembly in the printer needs service.
