Dear Sir, Kindly tell me how to remove cartridge from my printer HP 4200 and re assemble Thanks, V. Gopinathan


Turn the printer on.
Lift the lid that covers the print-head assembly.
The print-head should slide to a position from where you can "unlock" an ink-cartridge from the carrier, and remove the cartridge(s).

How to open H.P laserjet 1020 for cleaning the powder dust in printer


The only part of the printer that you ned to get at is under the toner cartridge. Open door, remove toner cartridge and vacuum dust. If you are referring to black toner dust on the fuser roller ( where paper comes out of printer ) that is alot harder job.

I recently aquired a HP psc 2410 all in one printer. Upon start up I got an error msg that the cartridges are jammed, unjam and press ok. Well there doesnt appear to be a jam. The cartridges slide back and...


There is little or no value in older printers.
However the unit has gots its positioning confused.
Try switching off and on printer several time, opening lid for cartridge change to see if it can synch itself again.

Print Quality Issue In magenta color in HP color laserjet cp3505n i hv to change cratridge but problem not resolve Pleae help us


I received a similar HP Laserjet Color Printer with same issue for repair/ maintenance a few months back.
Actually the problem is with the printer design not the magenta cartridge and it needs professional hands for servicing and cleaning. The mirrors which reflect laser beam get covered with dust and toner. hence the image is not produced properly. note that first magenta goes off, followed by yellow, then cyan and lastly black. this is because of the mirrors placement inside the printer.

Rest assure that the printer requires ONLY CLEANING OF THE MIRRORS, which are inside the printer.

Clean them yourself with dry n soft cloth (if you are familar with such tasks) or get it cleaned by any printer repair/ service professional. Please note that the mirrors, lenses and scanner assembly inside such printers is extremely complex and can get damaged very easily especially the mirrors.

Hope it would help, looking forward

Colours not lineing up


The problem is caused by dust on the lower mirrors of the laser/scanner assembly. The dust makes the magenta and often cyan to fade close to the side edges of the paper. The callibration process prints patterns of colors just around the sides of the paper path and checks them with optical sensors. If they are not in specifications the callibration is unsuccessfull and your problem comes up. The main reason for the dust to occure is the main fan, located on the bottom, right to the laser/scanner assy. This fan gets the dust from below the printer and trow it in the middle where the all imaging process takes place. The dust and some toner get airborn and reach lower mirrors.
To resolve:
1. Take the pritner apart, starting from the back cover, side covers and the metal frame with the boards at the back. The laser/scanner assembly is behind this metal frame. Remove it and open it.
2. Clean all the mirrors from dust with lint free cloth. You may use isopropanol or glass cleaner.
3. To make it permanent, you may cover all vents of the fan with sticky tape. Don't just disconnect it because the printer will get error "main fan malfunction". To cover them properly, I usually remove the plastic gratings. And, yes, this is absolutely safe for the printer. I'm doing this for years to the printers that come to my service.

My scanner fails to scan documents. It either generates a "warming-up" message OR "sorry, scanner could not be initialized. (Scanner parameter error.)" message.


there are many users facing this same error message.
there are options to solve the issue.the upper part of the printer is scanner.you have to remove that upper portion by removing the screws and internal locks on its inner layer.then check out if any dust is got collected on the scanner lens.the lens is a thin glass layer in the scanner that reads the document which you place on the glass.if the dust gets collected on the lens it will show this error messages.but if after cleaning it shows same message that means the internal board is got faulty.there is a mini circuit board beside the scanner glass.internally.so the upper scanner assembly needs replacement.in the scanner assembly set you get the new circuit board.scanner assembly means not the upper scanner glass it only includes the inner assembly and the circuit board of scanner assembly.the cost of new assembly is near to $40.you can get this assembly at any local printer repair shop.they have it in spare or they can easily get it from nearest service center of the hp company.
thanks.

The magenta cartridge prints very faint on half of page


Hi

I now know the reason for problem. It is in fact a design problem by HP. They have not protected the laser scanner unit properly. Toner powder can get into the laser unit. To cure the problem you have to strip down some of the printer. First remove the toners, Remove the back cover remove two PCB under the rear cover, then remove the supporting metal panel. Then removing the laser unit. There are two small spring metal cover plates that have to be removed to get the bottom two screws of the laser unit. Best to the lean the printer on its front as these plates are on the bottom of the printer.

When you have got that far, you have to remove a small spring and then undo just one screw that holds the laser unit plastic front cover.

When this cover is removed you can see the fancy optics of the laser unit. You will find a covering of toner dust all over, the angled mirrors and lenses. The bottom angled mirror having the most toner dust this is the magents mirror.

I used a camera lens cleaning brush to remove all of the toner dust. Shining a small tourch around will high lite the dust on the various parts.

When this is done then you have to re-assemble it all.

If everthing has been done correctly then you are back in business.

My HP 7110 Officejet says ''scanner failure.'' It will not let me fax or copy. How do I fix this?


If you can remove the glass, you need to clean the lamp and mirrors in the scan assembly, this error happens after the lamp ages and dust gathers on the scan mirrors. It's very expensive if you can even find a new scan assembly.
