    General Information After being idle for one hour the printer switches into its Energy Star mode where it consumes less than 45 watts of power. It “awakens” upon receiving data at any of its ports. The printer also features a closed-loop image density sensor system that allows it to auto-calibrate its color imaging so printing output remains consistent over the life of the print engine and its consumable supplies.

  • Page 223 Appendix Test Prints This appendix illustrates the test prints produced by the print engine. It also illustrates a number of defective prints and the reason for the defects. The Chapter 6 Troubleshooting topic “Printing and print quality problems” on page 6-24 discusses solutions to the problems shown in this appendix. Test Print consists of four 25% tint primary color bands.
  • Page 224 Test Prints Vertical line or scratch in print, single color If the scratch is of one missing primary color, then the trouble can usually be traced to a scratch in the developer roller of the missing toner’s toner cartridge. No toner is transferred from the developer roller to the photoconductive belt at the defect point.
  • Page 225 Test Prints Small, repeating light dot in one color This can usually be traced to a dent-like defect in the developer roller of the toner cartridge in question. The dents should be 1.5 inches (3.4 cm) apart or 1 inch (2.5 cm) for 1200 dpi printing. No toner is transferred from the developer roller to the photoconductive belt at the defect point.
  • Page 226 Test Prints Large, random light smudges Spots such as those illustrated are caused by fingerprints on the photoconductive or accumulator belt. Often, the smudges will gradually fade with additional printing. Alternately, the imaging unit will have to be replaced. Finger prints can be removed by applying some toner (any color) to the fingerprints and rubbing lightly with a cotton-tipped swab.
  • Page 227 Test Prints Faded, pale prints The imaging unit is old or has been exposed to too much room light. Replace the imaging unit. The image density sensors are not properly measuring the amount of toner transferred to the accumulator belt. Clean or replace the sensors.
  • Page 228 Test Prints One primary color faded or pale OR a single color has a dark vertical streak This indicates a problem with a single toner cartridge. Replacing the toner cartridge should fix the problem. If it does not, there may be a problem with the toner cartridge selector/eject unit.
  • Page 229 Test Prints Contamination of one color by another This is most noticeable on solid primary fills. This is caused by a defective photoconductive cleaning blade. The blade is not scraping off all of the untransferred toner from the previous pass of the photoconductive belt to the accumulator belt prior to the next toner’s transfer to the photoconductive belt.
  • Page 230 Test Prints Interpreting Service Print 2 Service Print 2 is useful for evaluating the condition of the imaging unit. With a properly functioning imaging unit and printer, you should see the following: 1. Diagonal lines. These two lines should be smooth and unbroken.
