HP 88 Black/Yellow Officejet Printhead in Retail Packaging
Review by Kirby Walker "AustinGuy" : Pinthead worked.

I have mixed feeling about this. The printhead solved my printing problems--gaps on the printed page--but it's only replacing a part that failed a little more than a year after being put into light service--just enough for the warranty to expire! I called HP customer service and they charged me $39 to tell me I have to buy a new printhead from them for $72. I found this one at Amazon for almost half the price (both are genuine HP parts). I did get my $39 refunded from HP but only after an hour long hassle that turned my opinion of HP from very positive to, well, they're just another computer company. Reality bites.

Review by T-Bone Kuz "sdsu98" : HP 88 Blk_Ylw Printhead for Officejet Pro L7590

HP 88 Blk & Ylw Printhead came as promised from Amazon. Easy to install but noticed you need to shake it before install to ensure it works right away. Mine worked right away without the shake. Lowest price I could find for this product but also check to ensure your printhead isn't still under HP warranty. The date is on one of the printhead sides. HP will send out a free one if it is.

Review by mpk : A junk.

I have used HP L7590 Officejet Pro for little over a year and I had to replace both print heads twice. HP suggested that I "abused" the unit... which means that average of 4 pages per day is too much for their equipment. HP had me replace both printheads ($80 apiece). Only four months later the printer experienced the same issue all over again. After 45 minutes on hold and brief (3 questions) inquire from HP rep I learned that printheads are probably fine, but the printer's hardware overheated and needs to be replaced. By the way: HP did not honor warranties on either printer or printheads. Frankly, I'm very disappointed with a product as well as service. Huge let down.

Review by E. Young : piece of junk lasted 41 days

This is the second time the black/yellow printhead has failed for me on the HP L7680 All-in-one printer. This time it lasted only 41 days -- home use with low # of copies printed. This particular printer is a clunky piece of junk and I won't buy HP again.

Review by S. Williamson : Under warrenty

HP had to replace it after a few uses. I got an error message on my printer (a problem with K/Y Printhead) that I couldn't clear off the screen. Called HP and after 1.5 hours of "troubleshooting" they agreed to fedex me a new printhead and it works great.

Review by Anil Saisbhan : Try the shake and clean before replacing

My L7580 started saying both my printheads had an error. I took them out and wiped both heads at least two or three times and rebooted the printer twice. Then it started saying the M/C one had an error. I took it out and shook it like a bottle of nail polish (needless to say some spilt on my flooring and my wife is pissed) and wiped the head with a napkin and methylated spirit. Stuck it back in and works! My printer is about two years old, but has not done much printing. So before you replace the heads if you get similar errors - do the shake and wipe first.

Review by Shannon : Works perfectly!

I was having trouble printing anything in black ink for a while - thought I just needed to replace the black ink cartridge, but I did and it still didn't work. Once I replaced the printhead, all problems were solved!

Review by Elizabeth A Patterson : Expensive, but needed it

The price here was less than anywhere else I could find, but my printer works much better with new printheads, printing much crisper than it was previously.

Review by Earl Willey : First was DOA

The first one was DOA. They overnighted another one that day, and that one is working perfectly.

Review by Stefano Rosellini "Stefano Rosellini" : Pay attention and do not waste time and money

I am very disappointed at HP and their L7590 Printer that uses the 88 printer-heads. I had a problem with printing the black and after having replaced the ink I proceeded to replace the yellow/black head. My printer has been used very slightly so I was very disappointed at the investment I had to make. I changed the head and after hours spent trying to get it to work I discovered that this is a known defect and that the problem is with the printer. HP is doing absolutely nothing to inform their customers and correct the issue.
If you are having a similar issue make sure that it is a printer-head problem and not something else.
