On the HP DeskJet 2855e, E0 through E6 are different control-panel problems. Read the full code and the nearby cartridge or Resume lights before changing a setting or ordering ink.
Match the complete code
HP lists the DeskJet 2855e in its 2800e family. Its exact-model US support page points to HP's 2800/4200/4900 blinking-lights guide. The table below summarizes that guide for this model; another HP family may use the same digits differently.
| Code | HP meaning | First safe check |
|---|---|---|
| E0 | Cartridge problem | Check which cartridge icon blinks. Reseat that cartridge and remove only protective tape if still present. |
| E1 | Paper width or size mismatch | Compare the job's paper size with the loaded paper; cancel or resume only after checking the setting. |
| E2 | Paper length mismatch | Compare the job's page length with the loaded paper and retry the document. |
| E3 | Carriage stalled | Open only the user-accessible front and cartridge doors; remove visible obstructions without forcing the carriage. |
| E4 | Paper jam | Clear visible paper from the documented path and restart after the jam is removed. |
| E5 | Scanner fault | Cancel the scan, retry once and restart if needed. HP notes printing may still work. |
| E6 | Printer error state | Power off, unplug for one minute, reconnect and turn on. Contact HP if it persists. |
Choose the right next step
For E1 or E2, fix the paper and document setting; a new driver or cartridge will not correct a physical size mismatch. For E3 and E4, follow HP's illustrated access path and stop at a sealed or hot area. For E0, do not buy ink from the code alone: read which cartridge icon is affected, reseat it and check HP's current compatible cartridge list for the exact 2855e before replacement.
When to use HP support
If E0 remains after the documented cartridge checks, E3 or E4 cannot be cleared without force, or E5/E6 returns after the listed restart, use the HP 2855e support page. Record the complete code and lights. Do not upload a Wi-Fi password, full serial number or unrelated printer data to this site.
