SECTION FIVE If Print Quality is Poor Use the printed self-test pattern to help you diagnose the quality of text and pictures being printed. Print quality problems are often indicated by broken or missing lines and dots in the printout. You can often solve print quality problems by using only the print side of the paper, envelopes, cards, or transparencies, or by loading a different paper type. (See Section 3 for more details on using paper.) If you observe a print quality problem, find the symptom in the following table that most closely matches your problem, then perform the possible solution(s). For each listed symptom, more than one solution is possible. The first solution given is the most probable corrective action for the symptom. However, if that solution does not solve the problem, perform the other solutions in the order they appear until the problem is solved. Symptom Lines or dots are missing from the characters in the printout, making the ink coverage inconsistent. For example: Solution The connection between the print cartridge and cradle is intermittent. Remove the print cartridge and reinstall it. The paper is inappropriate. Try another type of paper. See Section 6. The copper contacts of the print cartridge may be dirty. If the problem persists after you cleaned the cartridge as described on page 45, remove the print cartridge. Use a lint-free water-damp cloth to gently clean the copper contacts on the print cartridge and the print cartridge cradle. Do not wipe the ink nozzles. Reinstall the print cartridge, close the top cover, and perform a self-test. 2162044 Do not clean the print cartridge unnecessarily, because this shortens the print cartridge life. If the print quality remains poor after cleaning, install a new print cartridge. If the problem persists, see Contacting Customer Support on page 65. 58
