3 inches is approximately 70 or so mm so i would say you have a bad drum on your toner

27mm - charge roller - Replace toner
75mm - Photosensitive Drum - Replace toner
34mm - Developing Roller - Replace toner
39mm - Transfer roller - clean/replace transfer roller
57mm - Fuser Film - Replace Fuser
56mm - Pressure Roller - Replace Fuser

This should help. Good luck !

Cassette (Tray 2) paper pickup and feed rollers

To remove the paper pickup and feed rollers

1 Remove the cassette.

2 Locate the two rollers on the bottom of the paper pickup unit (above the cassette). The pickup

roller is the smaller roller, and the feed roller is the larger roller.

3 Pinch the tab on the end of the cassette pickup roller (callout 1), and pull the roller out.

4 Pinch the tab on the end of the cassette feed roller (callout 2), and pull the roller out.

Note Always replace the cassette pickup roller and the cassette feed rollers at the same time. Also replace
the separation roller (located in the paper cassette) when replacing these rollers

If the mark is persistent on each page and repetitive with very precise spacing, you need to determine which roller it's coming from. It could be coming from the transfer roller, before the fuser, the fuser itself, or the fuser pressure roller. Measure the spacing distance of the mark(s), then measure the diameter of the 3 above mnetioned rollers, multiply by pi (3.14159265) and compare the results to determine exactly which roller is causing the issue, then replace that particular roller. Hopefully it's not the fuser as you'd be better-off replacing the fuser film (main fuser roller lining). The fuser and pressure roller are a pain to source, and run abou $65+ for the pressure roller, and about $90+ for the fuser, not to mention this 2 last rollers will take about 1-1.5 hours to replace. They are not hard to replace using common tools. Don't forget to locate the printer service manual over the internet first.

Hi Ranji,
Thank you for contacting Fixya.
The life span of the Pick roller is about 200,000 sheets or one year. Use Abrasion counter on the operator panel to estimate when the Pick rollers need replacement. The life span may be decreased by as much as half when carbonless sheets are frequently read. To replace Pick Rollers, please follow the steps provided below:
a. Remove Guide AASY. b. To remove the Pick rollers, turn the stopper counterclockwise. c. To remove the Pick roller 1, move the Pick roller 1 toward the left then lift it. d. Right after removing the Pick roller 1, remove the Pick roller 2 with the same way. e. To attach the new Pick rollers, place the Pick roller 1 from right above the groove for the Pick roller 1. Put the shaft of the Pick roller 1 into the groove. Then, slide the Pick roller 1 toward the right side. A Pick roller 1 has the groove in its rubber. Make sure that the bushing is securely fixed to the grooves. f. Attach the Pick roller 2, then slide the Pick roller 2 to the right. Make sure that the bushing is securely fixed to the grooves. g. Turn the stopper clockwise to secure the Pick rollers.
Hope the above information is helpful.
regards,
TechSatya

sounds to me like the Pick up rollers need to be replaced, you can try to manually clean those rollers with some rubbing alcohol and some q-tips and gently clean those rollers, if that doesn't help then the rollers need to be replaced. You can usually find replacement pick up rollers online

Hi clwest: I hope that this will help you.

Transfer Roller is at End of Life
■ Print the Supplies Usage page to verify the remaining life and Transfer
Roller install date.
■ Cycle printer power.
■ If the problem persists, follow the procedure below
Note
Look at the clear plastic window on the Transfer Roller. If toner is present in the
center of the window the Transfer Roller is at end of life and needs to be
replaced. If no toner is visible, try cleaning the CTD (ADC) Sensor.
The “Transfer Roller is at End of Life” is a warning. “Replace Transfer Roller” is
a hard stop.
