Table 7-1 Pre-troubleshooting checklist (continued) ● ● Print cartridges ● ● ● ITB and fuser ● ● Covers ● Condensation ● ● Miscellaneous ● ● ● ● Are the paper guides aligned with the media? Is the paper tray correctly installed in the product? Is each print cartridge correctly installed? Are original HP print cartridges installed? Are the cartridges damaged? Are the ITB and fuser correctly installed? Is the ITB or fuser damaged? Are the top cover and front cover closed? Does condensation occur following a temperature change (particularly in winter following cold storage)? If so, wipe the affected area dry or leave the product on for 10 to 20 minutes. Was a print cartridge installed soon after being moved from a cold to a warm room? If so, allow the product to sit at room temperature for one to two hours. Check for and remove any non-HP components (print cartridges, memory modules, and EIO cards) from the product. If hardware or software configuration has not changed, or the problem is not associated with any specific software, contact the Customer Care Center (see chapter 1). Remove the product from the network, and ensure that the failure is associated with the product before beginning troubleshooting. For any print-quality issues, calibrate the product. See Calibrate the product on page 479. Troubleshooting checklist If the product is not responding correctly, complete the steps in the following checklist, in order. If the product does not pass a step, follow the corresponding troubleshooting suggestions. If a step resolves the problem, you can stop without performing the other steps on the checklist. 1. Make sure one of the following messages display on the control panel: READY, PAUSED, or SLEEP MODE ON. If no lights are on or the display does not say READY, PAUSED, or SLEEP MODE ON, see Power-on checks on page 345. 2. Check the cabling. a. Check the cable connection between the product and the computer or network port. Make sure that the connection is secure. b. Make sure that the cable itself is not faulty by using a different cable, if possible. c. Check the network connection. See Solve network printing problems on page 354. 3. Ensure that the print media that you are using meets specifications. ENWW Troubleshooting process 343
