SOURCE: oki c5250n paper jam

Unfortunately this may require and engineers visit. If you pull down the MP assembly by using the handle in the middle at the front of the printer you can then see a small "gearbox" at the right hand side of the transfer belt. This is common to feeds from both trays and could be worn. If you remove tray 1 and temporarily tape up the sensor arms to fool the printer into thinking it has a full tray installed, you can the test, by applying a little pressure to the feed roller, to see if it positively moves forward or if you are able to stop it turning. On a brighter note, you may just need new rollers instead of cleaning them.

OKI MICRO LINE 321 TURBO REAR FEED PROBLEM


Have you tried taking out the Platen Roller (big smooth one) and washing it??? Soapy water is fine as long as you rinse & wipe it down to get the soap off... Sometimes the platen rollers slip when dirty and they can cause similar jams.

One of my employees use an Oki B4600. When she tries to print, it kicks the main tray out. This results in paper not being able to feed then it says paper jam (even though there is not an actual jam). Any...


Try to clean every rubber roller in the printer. Make some soft "paper" wet with vinniger (Juuice from grapes (not to drink but for in salad's)) and rub it over the rollers. So they can transport paper better.
If possible, removing the rollers, and then cleaning.

How do u remove the roller bar that the paper feeds thru if something is stuck underneath it?


Step 1

(1) Pull off the platen knob 1.

(2) Open the access cover Assy 4 toward the front to remove.

(3) Lift up the sheet guide Assy 5 to remove.

(4) Turn the change lever 2 toward the bottom position.

(5) Insert a flat-blade screwdriver into grooves of frame (5 places for ML 321, 4 places for ML320) and twist to disengage claws of upper cover 3.

(6) Raise the front side of upper cover Assy 3 and shift toward the rear to disengage claws of frame (6 places for ML321, 5 places for ML320).

(7) Raise the upper cover Assy 3 to remove.

(8) To install, follow the removal steps in reverse order.

Note on installation:

Match the posts A at both sides of the sheet guide 5 with the arrow marks on the upper cover. Push the guide into the cover.

Step 2

(1) Open the access cover 1.

(2) Lift up the sheet guide Assy 4 to remove.

(3) Tilting the pull-up roller Assy 2 toward the front, remove it from the shaft of platen Assy 3.

(4) To install, follow the removal steps in reverse order.
Note: Remove the sheet guide Assy 4 before installing or removing the pull-up roller Assy 2.

Step 3

(1) Open the access cover.

(2) Pull up and rotate the head clamp 1 to unclamp the printhead 2 as shown in fig. 3.3.1.

(3) Disconnect the printhead 2 from PC connector 3 and remove.

(4) To install, reverse the removal steps.

Notes on installation:

(1) Insert the printhead 2 into the PC connector 3 while pushing it against the carriage frame 4.

(2) The head clamp 1 must be securely sandwiched between printhead 2 and carriage frame 4 as

shown in fig. 3.3.2 below.

(3) Be sure to check the gap between platen and printhead (see 4).

(4) Be careful not to touch the print head while it is hot.

Important: There is a shim on the carriage frame 4, which hangs over the platen side of the frame. Be sure to replace it correctly. Improper positioning of this shim will severely affect the printhead gap.

(2) Open the pull-up roller cover 1.

(4) Loosen the screws holding the carriage assembly to the carriage frame--this allows more play between the printhead and the platen.

(5) Raise and remove the ribbon protector 2.

(6) To install, follow the removal steps in reverse order. Be sure to replace the shim in exactly the

same position as it was before disassembly.

(7) Remove the platen Assy 4 from the base frame.

(8) To install, follow the removal steps in reverse order.

OKI c5200 fuser is jamming, How to CLEAN IT b4 I try replacing it


There are not set instructions to clean the fuser rollers on the 5K range of printers from Oki, this is designed to be a consumable that is replaced at regular intervals through the printers life. this means there is little access to the rollers. Firstly, remove the fuser from the printer and allow it to cool down. At the rear of the fuser, on most models there is a flap that can be opened to give very limited access to the rollers. All that can really be done is to wipe the rollers with a soft cloth to remove any debris that has built up and turn the rollers using the gears on the side. The blue lever on top of the Fuser can be used to separate the rollers to make the task a little easier.

Paper keeps getting stuck in the fuser. Do I need to replace the fuser? I've never replaced it. It's about 3 years old. The paper gets part way in and is folded like an accordion. I've cleared it about...


If it's 3 years old, it might need replacing.

There are two factors. One is that the fuser (hot) rollers get contaminated with toner residue, resulting in them getting sticky. The sheet sticks to the roller, and instead of being fed straight through, it gets bent with the direction of roller rotation, and is pushed under the separator pieces.
The second is that the separator "tongues", that should facilitate separating the sheet from the roller and directing the paper to the output, deteriorate over time. They are plastic, and subject to prolonged heat, so after some time they tend to lose their shape, get cracky etc.

Replacing the fuser is not a hard task, OKI is rather modular in it's construction. The instructions should come with the new fuser unit, and also you can look for directions on OKI website.

Good luck :)
