Print-Quality Troubleshooting Predominate Light Stripes Troubleshooting Procedure Step Questions and Actions Yes 1 Clean the exit path and Stripper Blade with a Complete. lint-free cloth. Did this correct the problem? 2 Remove the Drum Maintenance Kit and wipe Complete. the clear plastic wiper blade with a lint-free cloth. Did this correct the problem? No Go to Step 2. If the problem persists, follow the steps for "Random Light Stripes" on page 5-3. Smudges or Smears Smudges or smears appear on the page. The likely cause is ink residue in the media path. Check for residue on the rollers, Stripper Blade, guide ribs, or inside the Preheater. High coverage images with small margins may leave ink debris on the Stripper Blade which is then re-deposited on other pages. This condition usually self corrects (the debris is "cleaned" off the blade by lower coverage images). Note To avoid future problems, remind the customer to select "2nd Side" as the paper type if manually printing duplex with preprinted solid ink images on the reverse. This reduces Preheater temperatures to prevent partial melting of the preprinted image. Initial Actions ■ Check that the media used is supported. ■ Run the Remove Print Smears routine from the Control Panel. ■ Check the exit path for debris or contamination.
