My Officejet 8500 Pro always goes to "printer off-line" after several minutes of nonuse. When I restart it, it goes through several minutes of set-up, includinging annalysis and "cleaning printhead". When it finially finishes, it prints what's in the que. I had a Photojet B210 that did the same thing. Anyone know what the fix is?
This printer will clean the printheads, as this is normal and is required to keep the printheads from not getting clogged. For more information follow this entire HP document on Ink Usage in Inkjet Printers.
Please post your results, as I will be looking forward to hearing from you. Have a great night!
