Question about HP - HP Photosmart 8250 printer

1 Answer

I get horizontal gaps in printing, gaps about 0.2 in. high and spaced regularly about 0.5 in. apart, regularly all the way down the page. So it slices off top or bottom of many lines. When I rotate the format from 'portrait' to 'landscape,' instead of these gaps I get a blurry effect: every letter is shadowed by a lighter copy about a sixteenth of an inch higher or lower. I've tried the 'tools-alignment' and 'clean printerhead.' Any suggestions? Thanks! Felix

Tip

When u print if u r getting the Horizontal or vertical line then follow these...


If the print is a dismal gray rather than a sharp black, you are probably almost out of toner. This can manifest itself evenly across the entire page or in splotches or stripes, depending on the printer.
Sometimes you can wring a little bit more out of a toner cartridge by taking it out and gently shaking it from side to side (never up and down, as toner can spill out). You can also try turning up the printer’s contrast adjustment, if it has such a knob (usually on the back side if it exists). Faded print can also result from a dirty corona wire, because a dirty wire inhibits a full electrical charge from being passed.
If the printouts are consistently varied in density, and you have to frequently remove the toner cartridge and shake it to redistribute the toner inside it, make sure the printer is sitting on an even, flat surface.
Horizontal black lines
A horizontal black line on the printout is probably the result of a dirty or damaged roller. There are lots of rollers in the printer, and you can use the space between the lines on the page to determine which roller is causing the problem. Measure the distance between the errant black lines on the page and then use Table A to determine which part might be causing the problem. Table A
Distance between lines
Faulty part
0.5”
Registration assembly
1.5”
Upper registration roller
1.75”
Lower registration roller
2.0”
Toner cartridge developer roller
2.56”
Lower fusing assembly roller
3.16”
Upper fusing assembly roller
3.75”
Toner cartridge photo drum
Regularly spaced splotches
If there are evenly spaced black spots but they don’t extend all the way across the page, the problem is probably a scratch or flaw in the drum or a build-up of toner on the fusing roller. If the spots are less than three inches apart vertically, it’s probably the drum, because the drum has a larger diameter than the fusing roller.
Vertical black line on edge of page
This can indicate an almost empty or faulty toner cartridge or (less frequently) some spilled toner inside the printer.

Regularly spaced horizontal lines suggest that there is a defect on the drum in the printer. I would suggest changing the drum to see if that will fix the problem.

Black horizontal lines across pages


If they are the same distance apart every time then suspect the problem to be caused by the components in this order First the drum that is in the print or xerographic module, the charge and cleaning roller are located in that module also. So I suspect that first.its .Located above and to the right of the toner cartridge. Secondly it could be the roller on the toner cartridge, that would occur probably every 1 1/2 to 2 inches apart, the drum would cause the defect about every 3 inches. It less likely could be coming from the fuser, and if the fuser was causing that you should also have a lot of jams. There is also a transfer roller on the right hand door that could be causing it, but that would be exceptionally rare.
If the lines are random and have no consistant spacing, I would suspect the power supply then the laser.

Printer prints white thick blank lines


1- black lines are from the drum: it has burnt out on that particular spot and rotates

2- the white horizontal gap space if it is not you skipping space is also from the drum

3-the white Vertical is most likely from the developper (unit that has the toner and is against the drum, look at the roller it should be solid black, maybe there is something on it : hair paper etc....
