Table 7-14 MP modes under the Optimize submenu (continued) TRAY1 Set the mode to ALTERNATE if you are seeing marks on the back side of the paper when printing from Tray 1. This sets the product to initiate a clean sequence every time a job finishes when the product is set for Any Size and Any Type for Tray 1. ENVIRONMENT Set to LOW TEMP if the product is operating in a lowtemperature environment and you are having problems with print quality such as blisters in the printed image. LINE VOLTAGE Set to LOW VOLTAGE if the product is operating in a lowvoltage environment and you are having problems with print quality such as blisters in the printed image. TRACKING CONTROL Improves color stability by adjusting the bias voltage. Make sure this mode is set to ON. UNIFORMITY CONTROL Set to ALTERNATIVE 1 to improve uniformity on any paper type. Set to ALTERNATIVE 2 to improve uniformity on normal and light paper types. Set to ALTERNATIVE 3 when the other alternatives do not correct the problem. NORMAL PAPER Set to SMOOTH when printing on smooth paper of normal weight. HEAVY PAPER Set to SMOOTH when printing on smooth, heavy media types. ENVELOPE MODE Set to REDUCED TEMP if envelopes are sticking due to moisture in the envelop adhesive. RESISTANCE MODE Set to Up to resolve print-quality issues caused by poor secondary transfer in low-humidity environments with resistive or rough surface media. HUMIDITY MODE With glossy film, set to High when the product is in a highhumidity environment and print-quality defects occur on HP Tough Paper or Opaque film. With transparencies, set to High when the product is in a highhumidity environment and print-quality defects occur on color transparencies on the first page of a print job. With all other paper types, set to High when the product is in a high-humidity environment and light density occurs on the first page of a print job. PRE-ROTATION MODE Set this feature to ON if horizontal banding occurs on pages. FUSER TEMP MODE If you are seeing a faint image of the page repeated at the bottom of the page or on the following page, first make sure the Paper Type and Print Mode settings are correct for the type of paper you are using. If you continue to see ghost images on your print jobs, set the Fuser Temp feature to one of the Alternate settings . Try the ALTERNATE 1 setting first and see if it solves the problem. If you continue to see the problem, try ALTERNATE 2 and then ALTERNATE 3. Using the ALTERNATE 2 and ALTERNATE 3 settings might cause an extra delay between jobs. PAPER CURL MODE Use in high-humidity and high-temperature environments. The REDUCED setting decreases fuser temperature and increases the interpage gap. RESTORE OPTIMIZE Return all settings to the factory-default settings. ENWW Use manual print modes 493
