Troubleshoot print-quality problems This section helps you define print-quality problems and what to do to correct them. Often print-quality problems can be handled easily by making sure that the device is correctly maintained, using print media that meets HP specifications, or running a cleaning page. Print-quality checklist Follow the checklist to solve general print-quality problems. ● Process a cleaning page to clean the fuser (see Clean the fuser on page 44). ● Check the printer driver to make sure that you are using the best available print-quality option (see the user guide). ● Try printing with one of the alternative printer drivers. The most recent printer drivers area available for download from www.hp.com/go/LJM3027mfp_software or www.hp.com/go/ LJM3035mfp_software. ● Clean the inside of the device (see Clean the device on page 40). ● Check the paper type and quality (see Media specifications on page 15). ● Check to make sure that Economode is off in the software. ● Troubleshoot general printing problems (see Troubleshoot general printing problems on page 243). ● Install a new HP print cartridge, and then check the print quality again. (See the instructions provided with the print cartridge.) NOTE If the page is totally blank, check to make sure that the sealing tape is removed from the print cartridge and that the print cartridge is installed correctly. Newer devices have been optimized to print characters more accurately. This might result in characters that look lighter or thinner than you are used to from an older device. If the page is printing images darker than those from an older device, and you want the images to match the older device, make these changes in the printer driver: on the Finishing tab, select Print Quality, select Custom, click Details, and select Print Images Lighter. 248 Chapter 6 Troubleshooting ENWW
