Common questions about HP ENVY Photo 7855 ink
Should I buy HP 64 or 64XL?
64XL. The XL black is rated for about 600 pages, three times the standard, and the XL tri-color about 415 versus 165. See Is XL ink actually worth it? Standard vs. XL with real numbers.
Can I mix standard and high-yield cartridges?
Yes. Each cartridge is read separately, so any mix of standard and high-yield sizes works.
What other printers use HP 64/64XL?
The same cartridges fit the ENVY Photo 7858, ENVY Photo 6255, ENVY Photo 7155, and ENVY Photo 6252 and 7164. If you own more than one, a single stock covers them all.
Will other HP cartridges fit the ENVY Photo 7855?
No. HP 62, 63, 65, and 67 cartridges are different shapes. HP 303 is the international version of HP 64 and is region-coded for printers sold outside North America. Always match the number on your current cartridge.
Are compatible or remanufactured cartridges safe for the ENVY Photo 7855?
Yes. Quality compatible and remanufactured cartridges print like OEM, and using them doesn't void your warranty under U.S. law. HP firmware updates can reject some third-party chips, so turn off automatic firmware updates before you switch. If you see a used or non-HP cartridge message, choose OK or Continue.

How do I replace the ink in the ENVY Photo 7855?
Turn the printer on and open the cartridge access door; wait for the carriage to move to the center. Push the empty cartridge down gently to release it and pull it out. Unwrap the new cartridge and remove the plastic tape covering the nozzles (don't touch the copper contacts or nozzles), then slide it in at a slight upward angle until it clicks. Black goes on the right and tri-color on the left. Close the door and let the printer align. Step by step: How to change the ink in an HP printer.
Why are ENVY Photo 7855 prints faded, streaky, or missing a color?
On this printer the print head is part of each cartridge, so a fresh cartridge often fixes nozzle problems. First run the printer's cleaning tool once or twice. If one color is missing from the tri-color cartridge, that color is empty and the whole cartridge needs replacing.

Can I print with only one cartridge?
Often, yes. Many HP printers switch to single-cartridge mode if one cartridge is removed or empty, printing black-only or color-only more slowly. Replace the missing cartridge soon to protect the nozzles. See HP printer not printing black: what actually fixes it.
Does the ENVY Photo 7855 fax and scan?
Yes. It prints, scans, copies, and faxes, with an automatic document feeder, automatic two-sided printing, and a separate photo tray.
Does the ENVY Photo 7855 work on Wi-Fi?
Yes. It connects over Wi-Fi and works with the HP Smart app. If it keeps dropping off the network, make sure it's on a 2.4 GHz band. Setup help: How to connect a printer to Wi-Fi.
