Question about Office Equipment & Supplies
Here is the problem. I ran out of black ink in my HP L7590 AIO printer, faint black print with white streaks. Installed new printer cartridge (alas aftermarket from LDProducts... used one of their cartridges before with no problem). The printer refused to print black. Cleaned the head as per instructions several times, automatically and by hand with cleaning solution. Result is the same... First page prints ok (the black is a little light, not deep black as before), second page prints about half and then goes lighter and streakier. Finally looked at the tubes going to the printhead. All of them are full, except the black... has a nice long stretch of no ink. I tried inserting and reinserting black ink cartridge. I even opened another new cartridge and put it in. To no avail, the black ink is apparently not pumping to the print head. The other inks appear to deliver o.k. to the printhead, their tubes are full... no bubbles or empty stretches like the black line. Any suggestions on what to try next?
Cheers - Richard same problem with the HP Officejet Pro L7500 InkJet Printer

Turn off the device after removing the printhead
After removing the printhead, turn off the device, wait about 20 seconds, and turn it on again without the printhead installed. After it has restarted, reinsert the printhead.
it will go through this long routine of perhaps 20 min or so. after its compleate it should print great.
