When printing color, only prints shades of red

I have had this printer forever with no issues. Recently, the color printing started to change .. as if the color cartridge was near empty. After only a few more print jobs and copies, it started printing in only shades of red (the black still works). I thought it was a fairly new cartridge but nonetheless, I installed a new color cartridge (HP 23) and it continues to print only in shades of red. I can't imagine I have 2 faulty catridges so I am thinking it is something with the printer (it is almost 10 years old!). Any suggestions?

Re: When printing color, only prints shades of red

I had the same problem and went through TWO, count em, TWO HP cartridges before trudging off to Office Max and buying one of their knockoffs. Guess what? Yep, it worked. So, HP must've put out a bunch of bad 23 cartridges, from all the complaints I have seen online, either overfilled with red or only filled with red. What a pain at the price!

Wiping and cleaning didn't seem to work. I do believe these babies are filled wrong. I suppose if I whined enough at HP they would replace them, but I doubt it as their inclination would be to say I bought recycled (I didn't). Eh.

My HP Office Jet printer is about 10 years old. Just recently it has been printing only in shades of red. No other color except black works good? I have changed the cartridge twice and same thing, so...

Hello and Welcome to FixYa!
Sir if your printer just prints red shades then it Most likely this is a print head issue. The print head is what the cartridges sit in inside of the printer. To attempt to resolve it, do the following:
(1) Open the printer and wait for the carriage to slide over. If for some reason it does not follow these instructions:(a) Unplug the printer (b) Manually slide the carriage over until you can get the ink cartridges out.(2) Remove the ink cartridges from the print head.(3) Use cotton swabs dipped in hot water or a mix of hot water and isopropyl alcohol to thoroughly clean the print head.(4) Repeat this until there is no ink residue coming off on the cotton swab.(5) Once finished, allow to dry and replace the cartridges(6) Try to print something now
If that does not work then you have one of two possibilities:(1) One of the ink cartridges is defective and causing the error(2) If it's definitely not that, then the print head will need to be replaced.
I hope this solution helps you.Don't hesitate to let me know if you have some confusion.
Sir, Your Rating as Maximum Stars and Words of Appreciation will be esteemed.
Thank you for taking my service.

Just recently everything printed is some variation of a shade of green. Have tried to adjust color settings on the control panel of computer

Good day!clean the printer and the cartridge if it can change the color..if still not..replace with a good cartridge..if still..your printer head cannot mix anymore colors.

Printer prints colours in different colours

Either you are out of red ink or the print head is getting plugged. Most printers substitute the nearest available color when a color runs out or the head is plugged. As some shades of red are made with yellow mixed, it therefore prints only in yellow if red is unavailable.

Wont print out document in blue print

Sorry your having this issue. Because Blue is a lite shade of Black, or a combination of red yellow and green ???? Point is even if you have only a black ink cartridge, or only color cartridge. Blue should be visiable and able to print.
Good luck, jasahasch

Ink Color Issues

Did you change any of the configurations on your printer. Most photo printers have color settings that are media dependent. It sounds like you might have it set to print on regular paper but not on photo paper. There are a lot of settings that you can accidentally change on a printer so I would suggest uninstalling the printer then reinstalling it and see if that is the issue.

Changes color when printing

your other color cartridges are running nearly empty, perhaps. if only 1 cartridge in this machine, the same thing has happened (multi-chambered color cartridge)
