My boss want to replace the black ink cartridge for one that prints color. Can this be done with the HP 12-a cartridges? HP Laser jet 1022


Unfortunately laser printers don't work this way. The laserjet 1022 was designed for black and white prints only. In order to do color printing with a laser printer you will need to purchase one that is designed to print in color. The laser printers work a bit differently than the inkjets - the laser printers have 4 toner cartridges, one each for Cyan, Magenta, Yellow, and Black, that work together to print a full color page. With the old inkjets you could just replace a black cartridge with a color one.

So, short answer: Sorry but no you can't make a laserjet 1022 print in color. :)

I would recommend looking at an entry level color laser printer from hp, such as the CP2025 (http://h10010.www1.hp.com/wwpc/us/en/sm/WF25a/18972-18972-3328060-15077-236268-3673580.html) if you are looking into purchasing a color laserjet.

Hope this helps

Hp 4250 laser jet vertical streak ghost image


Hello,
The problem you are having is caused by the fuser. The fuser is the part in the printer that heats up and basically melts ( fuses) the toner to the page. The fuser has a heat roller that is coated with teflon, your fuser coating has worn off in spots so the toner is sticking to the roller and causing the ghost image. You will need to order a replacement fuser. You can do a search on Google to find a replacement, the parts number is RM1-1082.

I hope this helps, if so please rate our solution.

HP Laserjet 2820 Streaks on Page


Hi,

There are 3 parts to the imaging process that could cause your issue. You have the toner (x4), the imaging drum unit (Q3964A) and the fuser unit. If you are getting streaks from all colors, one or more these parts are the issue.

Let's start with the easy stuff:

Open the cover as if you were replacing toner where you can "visually" inspect the toner and imaging drum. Pull the drum out and pull back the "plastic shutter" on the top, this will expose a green drum CAUTION! Too much exposure to light and touching it can cause damage. Just take a quick look trying to see if any of the lines on your page match any marks on the drum. Check the bottom half of the unit as well there should be a white section across the bottom, expect that as well.

Next look at the toner, if you can look at any other color but black it will help you look for the streak marks a lot easeier. If you couldn't see any streaks on the drum on toner cartridges, it's time to look at the fuser unit. Power the machine down and turn it around, unplug it then fold down the blue clips and CAUTION! the fuser heats the toner to the page so if it's been used recently it may be hot. once the clips are down, just pull straight back and look for the streak marks.

Sorry for the book, but I hope it helps.

Grey streaking on printed pages


Laser printers are charged using a drum which produces an electrostatic image. The drum could be unable to hold all of the 600v charge or be be scratched if the streaks are always in the same position the the drum is not holding the charge for the toner to attach to and therefore the drum is faulty and beeds to be replaced

Hp 4550 vertical line down center of page


From the service manual:


Vertical lines or streaks
 Check for a leak where light might be entering the printer.
 Check for circumferential scars on the photosensitive drum. If scars are present, replace the
drum cartridge if the line goes through all colors.
 Check for circumferential scars on the upper fusing roller. If scars are present, replace the upper
fusing roller if the line goes through all colors.
 Remove the imaging drum and inspect main charger or imaging drum for a contaminant, such as
a fiber, if the line goes through all colors.
CAUTION Do not expose the imaging drum to light for more than 15 seconds. The drum is light sensitive, and
exposure to light can cause permanent damage.
Vertical black lines
 The toner cartridge is defective.
 The toner cartridge is not seated properly.
 The fuser entrance is dirty.
 The fuser has scratches on it.
 This might be a repetitive defect. If so, the lines will repeat at a consistent interval down the page.
 The printer needs to be cleaned.
 There is a problem in the heating element.
Vertical white lines
 If white lines or streaks appear only in the black areas of the printed media, print several
configuration pages to clear the anomaly. If this does not clear the problem, check the sleeve
surface to confirm the defect, then replace the black toner cartridge.
 If white lines appear only in a particular color, try printing several configuration pages to clear the
error. If the error does not clear, check the sleeve surface to confirm the defect, then replace the
defective toner cartridge.
 There is a lack of toner or the toner cartridge is faulty.
 There is dirt in the laser path.
 The fuser is defective.
 A mirror in the laser scanner is dirty.

Prints black vertical line at bottom of page on every print. HP 8550gn


This should help -

Developer streak
Developer streak is characterized by a line of dark or missing toner
that stretches from the leading edge to the trailing edge. Replace the
toner cartridge corresponding to the color of the developer streak (for
example, if the streak is magenta, replace the magenta toner
cartridge).

Repetitive defects troubleshooting
Repetitive defects are defects that occur in the same vertical position
on the page, but not necessarily on every page. Most repetitive
defects are caused by problems with one of the following, and are
indicated by the positioning of the defect on the page:
 developer roller (at 38 mm)
 charging roller (at 44 mm)—see additional information under
“Charge roller set” on page 454.
 cleaning roller (at 56 mm)
 developer DSD wheels (at 65 mm)
 transfer roller (at 66 mm)
 transfer drum (occurs once per 11-by-17 inch or A3-sized page,
or every other letter- or A4-sized page)
 fuser (at 150.5 mm)
 imaging drum (at 195 mm)
 transfer belt (at 222 mm)

Black streaks on printout page


It sounds like excess toner has built up in or around the imaging drum. I would *carefully* remove the toner and drum (can be messy) and use some canned air to clean the inside out. If you are still getting these streaks, it might be time to get a new drum (DR 400) as you are supposed to replace the drum every 6 to 8 times you change the toner cartridge.
