Officejet Pro 6830: after a big black printing session yesterday, black printing has failed today

[LJ-Walton]

Yesterday evening I printed about 80 pages of mostly black text; the first 60 in black only photocopier mode, the last 20 in best mode, black-only from MS Word.

During the last few pages of the MS Word printing, the printing carriage speed slowed and the audible tones the printer emits whilst printing progressively become lower in frequency (i.e. printing sounds were progressively lower in tone or musical pitch with each page).

I cancelled the printing with a few sheets to go and then came back later in the evening to finish - and it printed normally with normal sounds.

This morning, black printing has completely failed with no error messages. I have an Instant Ink account so have tried replacing the black cartridge, multiple cleans and deep cleans, PC driver software download and reinstall - no change.

Colour prints pretty well, but black has completely failed. My printer is about 3.5 years old and apart from yesterday's sessions gets used quite lightly.

Any suggestions of comments appreciated

Follow these steps to print a Print Quality Diagnostic report.

As these are to do with Instant ink cartridges,  I would need to know few details regarding your instant ink account to help you get this issue sorted.
