Question about HP DeskJet 9800 InkJet Printer

1 Answer

Grey & Black Printing on everything

Whether typing letters or printing reports, the printer prints a line of black and then a line of grey and so on down the whole page. I have checked all areas of the properties and nothing works. Is this an installation problem or something else? Should I un-install and then re-install the printer using my software? Any ideas?

    Hi Mike

    Further to your recommendations regarding my printer printing grey and black. I ran a diagnostics page which showed that the black cartridge PEN Status was (Misint) and had no ink. The report itself was still printing in grey and black. I then changed the cartridge and ran another diagnostic. The same (Misint) appeared but cartridge showed 98%. The grey and black lines do not change.

    After the black cartridge primed, the printer ran the usual sheet showing black and various colour setting with the sharpness 'birds' at the bottom. This ran OK but the lines which should have been black showed top half grey and bottom half black throughout the page.

    The right hand red light on the printer continuously blinks all the time. I am told it did this from the moment the printer was first installed.

    Any further ideas as to what this might be? Is the printer itself working incorrectly or could it be the settings in our computer system?

    I am at a loss with this one!

it appears that the printhead has a problem. try cleaning the printhead, via software. usually in printer prefs. also try running a few test pages. to see if you have any colours at all. if it,s only printing in grey scale. i.e grey-black. check the colour cartridges ink has,nt run out or blocked the nozzles.
Hope this helps Mike@Compurepair.

    Hi Dai,

    Can you give me the make and model number of the printer please ?

    You should,nt have any lights flashing on the printer at all. This would usually signify 1:-A Paper Jam. Check to see theres nothing blocking the paper rollers. 2:- Low or No Ink. 3:- electrical or signal cable fault. Possibly re-installation of Software Drivers for the Device.

    Regards Mike@Compurepair.

Epson pro 4800 r prints grey not blank and says to set cartridge

I am having the same problem If anyone has an answer or whether judy you have found an answer.

If I do a greyscale strip to print my black is coming out as a dark grey. the bead off of the greyscale strip would appear that the pbk photo black is not actually printing.

This has been a problem for a few months but as I haven't been doing much printing didn't notice it just thought something was odd. Now I look at previous prints and the blacks are black I print it out now and it is a dark dark grey. Nothing has changed in my profiles or my workflow. I have tried hours of profile paper printing option changes and workflow adjustments but nothing changes, If I print 100 percent black from a file it comes out 95% grey I have tried it from three computers to clarify. It appears is a 4800 problem.
Perhaps it is not recognising that it is a PB catridge.

I have no idea.
I have tried adjusting the settings from the printer but there is no option to clarify catridge from the printer.
This is odd, if anyone has any idea.

Prints grey not black

I solved this problem but probably not what the printer manufacturer would recommend! The reason you are just getting grey is that the black ink cartridge is either empty or dried out from non use and only the color cartridge is working. I had the same problem after being away for 5 months. I put the printer cartridge in a bowl of warm water to disolve the dried out ink on the print pad. I dried off the cartridge with a soft cloth and then it worked perfectly.

Printing only in grey

Can you do simple copies in b/w without probs?

If yes, you might have checked the greyscale at the printer settings.
If no, do a quality test print (pressing ink etc.). If you cant read the instructions in black, the ph or circuit board is defectiv.
