If you suspect that the spring is weak definitely replace it. Typically the spring is replaced during biannual maintenance service. J.

Pass thru sensor and flag assembly:
The tray 2 option system board did not detect a piece of paper
actuating the pass thru sensor. Remove any jammed sheets of paper
from the printer and check the pass thru sensor and flag for proper
operation by running the appropriate Tray Sensor Test from the
diagnostics menu. If the test fails, check the sensor for correct
installation and the flag for proper operation. Also check the sensor
cable to make sure it is correctly connected to the option system
board. If incorrect, replace the tray 2 option pass thru sensor
assembly.

Check these parts for signs of broken or damaged parts,
contamination on the drive rollers or wear plate and wear or damage
to the drive shaft bearings. Check the drive roll assembly and skewed
backup roller for wear, slick spots, material buildup, and oil or grease
on the rollers. Also check for proper operation of the paper aligning
assembly. Repair or replace parts as necessary.

Faint print after installing new roll of paper


Is it thermal paper?

Try pulling off about 12" of paper and reprinting. Sometimes the outter layers are damaged somehow.

Is the spring on the roller bar good?

Canon pc 420 paper feeds only part way


I had the same problem. I found a parts diagram here http://techno-parts.org/canon/220/320_220.php which showed that the springs hold the bar down. On mine, on each side, one of the spring tabs was broken.

I made a metal pin for one side and insert a screw on the other. Be sure and wrap the spring over the nylon bushing.

Paper pulls to the right, jams, won't print, tried different paper still won't print


Hi,
Sounds like the feed rollers need cleaning.
Clean the feed rollers, lint free cloth,bottled water.
wait for them to properly dry

Revolve the feed roller bar as you clean them, to clean the feed rollers all the way round, remove all particles from them.

Check you ADF grips are set correctly, if not you will get mis-fed sheets. check the tray is sat properly too or mis-feeds.

Check paper size is correct in print properties too.
Should be good then
Try print.

Regards
Richard.

Spring came loose under the roller


Hi niffieprinti:
If you remove the toner cartridge again and remove the roller (Registration Roller) one side of the roller has a gear and the other has a silver bar, well one spring goes under the gear on the left side and the other spring goes under the bar on the right side of the roller. The springs apply pressure to the paper against the toner cartridge so that the image is clean and dark. if you have any further questions let me know.

Thanks

Paper roller the long bar where the paper goes under.


The most common issue is a black bushing at the rear of the machine breaks and the spring attached flys off. this is the #for canon 800-828-4040 and you can find a local service center thru them.

HP LaserJet 5200tn printer that doesn't print dark enough.


If that's okay, then these are the other possible causes:
Transfer roller is defective or incorrectly installed. If the
transfer roller loses conductivity, it cannot effectively pull toner from
the drum to the paper.Transfer roller is defective or incorrectly installed. If the transfer roller loses conductivity, it cannot

Action 5

Inspect the transfer roller for correct installation and contact. If the transfer roller is damaged, replace it.

High-voltage connector springs are dirty or defective.

Action 6

2. Check the laser/scanner shutter door for proper operation. If it is defective, replace the laser/scanner assembly.

Officejet 7310, ADF will not operate, no movement of upper roller


Lift up the cover to the automatic feeder.
You will see a spring on the side of the mechanism towards the front; remove the spring; that will allow you to lift up the little arm the spring was attached to and remove the roller or bar and the light blue/green plate just under it.
Then you will be able to see of there is any jammed paper, which which can be pulled out carefully with a pair of tweezers.
Some may be under the rubber rollers.

Hp laserjet 4250n paper jam in 13.01.00


According to the manual: "A 13.01.00 error message indicates that the media did not arrive at the pre-feed sensor (PS102) within the specified time." That usually means that the rollers fail to pickup the paper from Tray 2. Usually, cleaning the paper feed roller in the 500 sheet tray should fix this. While blowing out dust, you may have coated this roller with paper dust. A quick way to double check this is to power cycle the printer & try to print from Tray 1, the MP feeder tray (unless Tray1 has rarely or never been used...it might be a little tempermental as well). Regardless, this error is very common & is usually fixed by cleaning. Depending on usage, this roller is considered a customer replacable item (Part # RM1-0037-000CN) with a life expectancy of more than 200,000 pages. There are 3 of that type roller in the printer, but the one in the tray is usually the 1st one to fail. Hope this helps!
