What to check first
Step-by-step checks
- 1
Consumable check
Open the cartridge access area and reseat the installed cartridges carefully.
Start with the official recovery step before moving on to parts or deeper servicing.
- 2
Consumable check
Check that the cartridges match the printer family and are locked into place.
- 3
Consumable check
Retry with one small print job once the cartridge state looks normal.
Background
What this message usually means
HP uses E0 on the ENVY 6000 and 6400 family when one or both cartridges are not in a usable state. This is usually a cartridge-recognition or cartridge-condition problem rather than a deeper printer-mechanics fault.
Before the message
What users usually notice first
Messages like this often appear after the printer fails one of its normal startup, supply, or paper-path checks and cannot return to ready state cleanly.
Diagnosis
Likely causes
A cartridge is missing, faulty, or not seated correctly.
A recently installed cartridge is not being recognized normally.
The printer detected a cartridge state that blocks printing.
Service
When service or replacement is more likely
- -Treat E0 as a cartridge-state issue first, not as a paper-path or scanner problem.
Avoid wrong turns
Common misreads of this message
- -Treating the message like a confirmed failed part instead of a support clue about which system has stopped the printer.
- -Assuming any supply-related wording means the next step is automatically to buy a cartridge, toner, drum, or printhead.
- -Assuming no physical path issue exists just because no full sheet is visible at first glance.
