REMANUFACTURING THE HP LASERJET P2035 2055 TONER CARTRIDGE
By Mike Josiah
Figures above show the different physical sizes of the two cartridges. The cartridges are similar in design to the 1160/1320 car­tridges, but are not interchangeable.
The drum drive gear is a completely new system. The actual drive gear is a floating type that uses a ball and socket config­uration (as shown here).
There are also no screws used at all to hold the cartridge together. All the end caps and bushings are held in place by plastic welds. This sounds worse than it is though, it’s a little harder to take apart than a 1320, but not that bad.
The pin system holding the two halves of the cartridge togeth­er is similar to the HP-1160/1320. You will need to cut two small holes cut in the top to get access to the pins. The pin access-hole location on these cartridges is almost identical and the same methods you use for the 1320 should work here.
The printers released in this series so far are as follows: P2035 P2035n P2055d P2055dn P2055x
Cartridge troubleshooting as well as running test pages, clean­ing pages and some simple printer troubleshooting will be cov­ered at the end of this article.

First introduced in November 2008, the HP-P2035/2055 series of laser printers is based on 30-35ppm, 1200dpi Canon engine that comes standard with 16Mb Memory in the 2030 and 64Mb on the 2050 series. Two different cartridges are available for this series, the CE505A rated at 2,300 pages, and the CE505X rated for 6,500 pages. For the P2030 series, only the CE505A cartridge will fit.
SUPPLIES REQUIRED
110g HP-P2035 toner for the CE505A cartridge (2,300 pages) 290g HP-P2035 toner for the CE505X cartridge (6,500 pages) Replacement Chip
New Drum (Optional) Uninet #13372 - HP P 2035, 2055 Unidrum™ gearless recommended.
Wiper Blade (Optional) Dr. Blade (Optional) Magnetic roller (Optional) Sealing Strip (Optional) Cotton Swabs Isopropyl Alcohol Drum Padding Powder
REQUIRED SUPPLIES
Jeweler’s screwdriver Phillips head screw driver Small Common screw driver X-Acto knife with square chisel type blade (# 17) Flush Cutting wire cutters Dremel type tool with side grinding bit 3/32 drill bit Small #4 ¼” long self tapping screws
The pins in these cartridges are very similar to the HP-1160/1320 cartridges. The best way to remove them without damaging the cartridge is to cut two small holes. Other than the location, basically the same procedure as the 1160/1320 is used.

1. Remove the drum cover by prying up on each end. Note the spring position so that it can be replaced later.
2. Drill a shallow hole on each side of the cartridge as indicated by the arrows. Figures shown before drilling.
After drilling.

3. Push the pins out with a jeweler’s screwdriver. With the hole in this location by just pushing the screwdriver in, the pins will be pushed out. Remove the pins.
4. Separate the two halves.
5. With a flat head screwdriver, press the drum axle pin out from the inside of the cartridge wall as shown. There is a small shoul­der visible that the screwdriver should be pressed against. Make sure not to bend or damage the plastic wall and the plastic is thin and easily damaged. Remove the Axle pin from the outside with flush cutting wire cutters.

The drum hub on the opposite side is welded. The weld can be broken or drilled out, but there is a good chance that the hub will either warp if pried off, or will be hard to align if drilled out.
6. Remove the drum. This is a good time to look at the new drive gear(s). This is a completely new system. New drums and gears are being developed.
7. Remove the PCR and clean with your standard PCR cleaner. 8. Remove the 2 screws and the Wiper Blade.
9. Clean out the waste toner.

10. Coat the wiper blade with your preferred lubricant. Install the blade and 2 screws.
11. Re-install the cleaned PCR. Note that a new OEM PCR has a small amount of conductive grease on the black (contact) side.
12. Re-Install the OPC Drum and metal axle pin. The metal axle pin should have a small amount of conductive grease on the tip. Remove the old grease and replace before inserting the pin. Make sure the axle pin is fully inserted.

13. Slice the two tabs off each location as shown on the left (Seal) end cap. Use a square blade X-Acto knife to slice off the tabs.
NOTE: Both the end caps are plastic welded in place. The only way to open them up is to cut the welds and carefully drill them out. We have found the left (Non-Gear) side is the best side to do this on.
14. Using the 3/32” drill bit, drill out each of the two welds. Be careful to keep the drill straight as you drill in. Use a slow speed and only drill in no more than ¼”.
15. With a flat head screwdriver work the edge of the blade around the edge of the end cap and gently pry up the end cap. You will hear the remaining parts of the welds break free. The top weld will also break off now. Take your time with this.
16. Remove the magnetic roller assembly.

17. Remove the Magnetic roller drive gear. The end cap will keep the bushing in place.
18. Remove the DR. Blade and two screws.
19. Clean out any remaining toner from the hopper. Note the Dr. Blade seal. It is a sticky substance that can be clean with alcohol if toner gets on it.
20. Fill through the Mag roller opening with 110g of P2035 toner for the “A” cartridge, 290g for the “X”. There is not a fill plug in these cartridges.

21. If you are going to seal the cartridge, there is a white plas­tic shelf that needs to be removed. The shelf is held on with double sided tape. It can be gently pried off with a small screw­driver.
22. Re-install the white plastic shelf. If the adhesive is not working, replace it with a good double sided tape. This shelf helps with the flow of toner in the hopper.
23. Re-install the doctor Blade and two screws. 24. Clean the old grease off the contact plate, and replace with new conductive grease.

26. Install 2 small screws into the holes previously drilled out.
Leave the top 3rd hole alone! (This weld was broken when the end cap was removed). A screw here will interfere with installing the cartridge in the printer. In our tests, the two screws will hold the end cap on with no problems.
25. Re-assemble the toner hopper section. Place the Mag. Roller drive gear in place, install the magnetic roller assembly. Turn
the roller until the keyed end fits into the drive gear properly. Install the end cap, align the keyed magnet into the keyed slot on the gear side first, this will help in aligning the opposite end cap.

27. Place the two halves together, make sure that the two springs are aligned, and insert the two pins. Make sure that the pins
are slightly pushed in so that they do not interfere with installing the cartridge in the printer.
28. Install the drum cover; make sure the spring is situated correctly.
