Vertical lines on copies

[Kate444]

a black vertical line shows up on copies.  I’ve already gone into settings and did the 3 checks and those sample pages look good.  What else can it be?

Hi @Kate444,

I'd like to help!

Vertical or horizontal lines or color bands are typically caused by fingerprints, smudges, or debris on scanner parts, cartridge issues, or there is a power or calibration issue with the scanner mechanism.

Step 1: Clean the scanner parts

Fingerprints, smudges, dust, or debris on the scanner glass, under the scanner lid, or in the document feed slot can cause lines and color bands. Clean these parts with a soft, lint-free cloth sprayed with glass cleaner.

Read one of the following sections for steps to clean these components, depending on your printer type.

Printers with a flatbed scanner and lid

Clean the scanner glass and underside of the scanner lid with a soft, lint-free cloth sprayed with glass cleaner.

1. Turn the printer off, disconnect the power cord, and then lift the scanner lid.

2. Spray a soft lint-free cloth with glass cleaner.

      CAUTION: 

   To protect interior printer parts, do not spray cleaner directly on the glass or lid.

3. Wipe the main scanner glass, glass strip, and the white backing and automatic document feeder (ADF) strip under the lid until clean, dry, and streak-free.

   1. White scanner lid backing

   2. White ADF scanner lid strip (if present)

   3. Glass ADF scanner strip (if present)

   4. Main scanner glass

4. If any debris remains stuck to any parts, use your fingernail to scrape it off, and then wipe the area again.

      CAUTION: 

   Do not use a hard or sharp tool that can scratch the printer parts.

5. Reconnect the power cord to the printer, and then try making a copy.

Step 2: Clean the ADF rollers

If lines in copies persist when using the ADF, clean the rollers or separator pad.

1. Turn the printer off, disconnect the power cord, and then open the ADF cover.

2. Find any paper pick rollers and the separator pad inside the ADF. These parts have a rubber coating.

   

3. Lightly dampen a clean, lint-free cloth with distilled or filtered water, squeeze any excess liquid from the cloth, and then wipe any residue off the rollers and separator pad.

4. Leave the ADF cover open for two minutes to allow the parts to dry, and then close the cover.

5. Reconnect the power cord to the printer, and then try making a copy.

If the issue persists, continue to the next step.

Step 3: Reset the printer and check the power source

Reset the printer to clear certain error states, and then check the power source to make sure the printer is getting enough power to operate the copier.

1. With the printer turned on, disconnect the power cord from the printer, disconnect the power cord from the power source, and then wait 30 seconds.

2. If you are using a power strip or multi-plug adapter, connect the cord directly to a wall outlet to make sure the printer is getting enough power.

3. Reconnect the power cord to the printer.
