Verify Installed Options Under “Installed Personality” on the Configuration Page, look for options such as hard disk or DIMM types and sizes. Verify that the options which are installed in the printer are reflected on the Configuration Page. If an installed device is not shown, reseat the device and print a new Configuration Page. Image Quality When you are working with customers, obtain a print sample before you begin troubleshooting the printer. Ask the customer to explain the quality they expect from the printer. The print sample will also help clarify the customer’s explanation. Table 7-9. Image Quality Checks Image Quality Checks Action Does the problem repeat on the page?
Use the Repetitive Defect Ruler on page 7-73. Is the Toner Cartridge full and is it manufactured by HP? Check the Toner Cartridge using the checklist on page 7-55. Is the customer using print media that meets all HP paper specification standards? For more information about HP’s paper specification standards, see Chapter 1 of this manual and the HP LaserJet Family Paper Specification Guide. Is the print sample similar to those in the Print Quality Tables on page 7-58? Compare and perform the actions recommended in the Print Quality Tables. Is the problem on the Toner Cartridge Drum or the Transfer Roller?
Perform the Half Self Test Functional Check (page 7-74) to determine where the defect is. If a dark and distinct Toner image is preset on the Drum’s surface, assume that the first four functions of the electrophotographic process are functioning (cleaning, conditioning, writing, and developing – see Chapter 5), and troubleshoot the failure as a Transfer or Fusing problem. 7-54 Troubleshooting
