Paper blade which help the paper to push for print damage

Yes, it is a known issue on that model. Maybe the developer roller is damaged, so that is damaging the blade. It can also be caused by the paper stock.

AS I understand you have black stripes on the back side of the print, so if this is the case, the Image transfer cleaning blade need to be replaced. Part number is: Genuine Ricoh Aficio 2238C Transfer Belt Cleaning Blade Ricoh AD04-1081, AD041081

Verify the input tray is empty, and then check for paper jams, bits of paper, and other obstructions, gently removing any obstructions.Lift the top door or the front cover, depending on the product, to access the print carriage, and then check for any obstructions in the paper path.Gently remove any paper or other obstructions from the paper path you might find, and then close the print carriage access door.Open the rear access door.Gently remove any paper or other obstructions from the paper path.Check the spring-loaded rear access door rollers to verify that they are clean and can be rolled.check the paper rollers inside the rear access and verify that the rollers are clean and roll upwards.Check the star wheel assembly inside the printer on the output side of the carriage. Verify that it is in good condition and clear of paper bits or other obstructions. NOTE:The star wheel assembly is located inside the printer on the output side of the carriage. The star wheel assembly is a set of small, star-shaped wheels on top and rubber rollers on the bottom. The assembly grips the printed side of the paper, and moves the paper to the output tray after printing.Replace the rear access door and verify that the rollers on the door and the rollers inside the rear access of the product are "matched up" with each other.Press the power button to turn on the product.Step Three: Check the paper type Verify that only recommended paper is being used for printing. The recommended paper types and weights for most HP printers include: Plain paper, 20 to 24 lb (75 to 90 gsm) Legal size paper, 20 to 24 lb (75 to 90 gsm) Card stock, up to a maximum of 110 lb (200 gsm) Envelopes, 20 to 24 lb (75 to 90 gsm) Photo paper, 145 lb (236 gsm) NOTE:Supported paper weights and types vary by product.

Tap the stack of paper against a hard, flat surface, such as a table top, to make the edges even.Insert the stack of paper into the input tray.make sure that the stack of paper is flat in the input tray. Verify the right side of the stack of paper touches the right side of the input tray and that the stack is pushed completely into the tray.Position the paper guides firmly against the sides of the paper stack without bending the paper.Step Five: Test the All-in-One Follow these steps to print a self-test page. If the page prints successfully, the product is functioning correctly.Press the Setup button on the printer.Depending on what product you have, perform one of the following:Press the arrow key to select Print Report and then press OK.Press the arrow key to select Self Test eport and press OK.A test page prints.If the test page prints without damaging the paper, you do not need to take any other action.If the test page is damaged during printing, proceed to the next step.NOTE:For printers which do not have a Setup button, check the product documentation to find out how to print a self test page.Step Six: Contact HP If you have completed all the steps listed above and are still experiencing a problem, the rear access door or the star wheel assembly is likely damaged.

Hi chrisneil,

This issue is generally caused by dirty rollers. Dust, paper scraps, and grime build-up on the paper feed rollers can cause paper jams. Follow these steps to clean the paper feed rollers.

Step one: Clean the rollers

Gather the following materials:

1. A clean, lint-free cloth, or any cloth that will not come apart or leave fibers Distilled, filtered, or bottled water (tap water might damage the product) Clean, lint-free cotton swabs.

2. Disconnect the power cord from the rear of the product.

3. Press the tab on the left side of the rear access door, and then pull the door outward to remove it.

4. Lightly dampen a clean, lint-free cloth with bottled or distilled water, and then squeeze any excess liquid from the cloth.

5. Press the cloth against the paper feed rollers, and then rotate them upward with your fingers. Apply a moderate amount of pressure to remove any dust or dirt build-up.

6. Locate the pick roller on the left side of the product below and behind the paper feed roller.

7. Lightly dampen a clean, lint-free cotton swab, and then use it to clean the pick roller.

8. Allow the rollers to dry for 10 or 15 minutes.

9. Check the rollers on the rear access door. Make sure that the rollers are not missing, that they turn easily, and that they are springy when you press them. If the rollers are damaged, replace the door.

10. Reattach the rear access door. Align the door pins with the slots on the right side of the rear of the product, and then push the door forward, snapping it into place.

11. Press the On/Resume button ( ) to turn on the product.

Step two: Print a self-test report

Print a self-test report. See the section on how to use these solutions at the beginning of this document.

If the self-test report does not print when slowly pushing the paper farther in , repeat the previous steps to clean the rollers again. If the issue continues after repeated cleaning, skip the next solution in this document, and then service the product. If the self-test report prints when slowly pushing the paper farther in , try printing the original document again. The paper might not have been loaded far enough into the product. If the issue is resolved, there is no need to continue troubleshooting.If the paper only feeds through the product when you slowly push it farther in , repeat the previous steps to clean the rollers again. If the issue continues after repeated cleaning, skip the next solution in this document, and then service the product.

If the self-test report prints , try printing the original document again. If the issue is resolved, there is no need to continue troubleshooting.If the self-test report prints, but the original document does not , continue to the next solution in this document.If the self-test report does not print , try printing the report again. Listen for the rubber paper-pick rollers; you should be able to hear them rotating. Then, try slowly pushing the paper farther in until the roller engages to pick up the paper. Be careful not to push the paper in too far, which can cause paper jams.

Hope it helps.

Thank you for using FixYa.

Can You see the paper?? if so, try getting a small flat blade screwdriver,turn off your printer and unplug the power, dab the flat bit with a tiny bit of pritt stick, dab the offending paper and withdraw it from the machine, if not, try folding a piece of a4 in half, place the paper in the feed tray and gently feed the paper by hand, back and forth along the full width of the machine,being careful not to damage any sensors, you might be lucky and the piece of paper may work itself out, or at least dislodge and then come out when u print, failing this, its strip down or scrap it time!

Has to be a roller problem. First check that the drum is being cleaned properly by the drum blade, it is responsible for cleaning the leftover image of the copy/print before it ( when you remove or look at the drum you should not see an image or toner ,it should be clean , if not replace  drum and blade). Next check that the upper fuser roller is not damaged ( This is the rollers that heat up and fuse the image into the paper  ). If these check out it could be the erase array or laser unit ...Good Luck

Make sure the paper that is in the drawer matches the orientation and size indicated on thje Op Panel Display, If NOT, MAKE IT MATCH.

I had the SAME problem with my printer and after hours of searching on the web I found this solution on fixyourownprinter.com and it WORKED! I cleaned the contacts of both of the ink cartridges and then popped off the cover of the optical sensor on the side of the ink cartridges (black plastic cover over sensor assembly snaps off) there is a hole in the middle of the sensor, push it in with a thumb tack or toothpick and push up on sensor assembly and it will come off the side, clean the contacts on that and reassemble..the blue sensor light should come back on and you should be back in business.

You prob have a few small pieces of photo paper jammed in the printer somewhere. Try to take something small that you can push through the printer to make sure there is nothing hidden jamming the printer.

The following can cause bands (vertical on a normal page)


Faulty Toner cartridge
Faulty Drum Unit
Faulty Transfer Belt
Contaminated Fuser
Damaged or dirty LSU glass

I've also seen this sort of thing caused by a crusty build-up of toner on a wiiper blade on the Transfer Belt, and or Drum.
