Sharp AL 800 AL-800 AL-840 Operation Manual - Page 40

TROUBLESHOOTING Problem Possible cause Solution Background The paper may be too scatter damp. Copying or printing over uneven surfaces. Missing characters Thank you very much for buying a SHARP laser printer. This manual tells you how to set up, operate and maintain your new printer, and contains advice on how to get the best performance from the printer. The descriptions contained in this manual assume that you are familiar with the operation of your computer and with how to send files to be printed. Please use this manual along with the documentation for your computer hardware and software. Your new printer has been specially designed to give you high-quality, trouble-free printing performance. The printer driver software lets the printer communicate with your computer via an IEEE P1284 bidirectional parallel interface, so you can control all aspects of printing from the Windows Printer control panel on your computer screen. Printing speed is a maximum 4 pages per minute at resolutions of 300 x 300 dpi for the JX-9200 and 600 x 600 dpi for the JX-9210. Consideration has also been given to ecological and environmental factors. Your printer features low power consumption, and after printing is completed it switches to a standby mode which complies with the US EPA Energy Star program. Moreover, no harmful ozone is produced during printing, and the toner self-recycling technology ensures that no toner is wasted. Printer operation is also very quiet: the printer generates less than 45 dBA of acoustic noise during printing, and during standby mode the noise level is no higher than the background noise level. Despite being packed with so many features, the printer is very compact. Its footprint is no larger than a single A4 page, and the total weight is approximately 5 kg, meaning that it is easy to transport and set up. The 100-sheet multipurpose tray is also located at the top of the printer to save space and to make inserting the paper easy. Most software applications will let you adjust the margins to have around the edges of the paper that you will be printing on. The area inside the margins then becomes the "printable area". The Windows Printer Driver specifies the minimum values that you can set for these page margins. These minimum margin settings vary depending on whether you are printing from a Windows application or from a non-Windows application in PCL emulation mode. The following illustration and tables show the minimum settings that can be made in your software applications in both Windows and PCL modes. Operating environment (temperature, humidity) is not proper. The paper may be too damp. The drum may be dirty. Try copying or printing with a different batch of paper. Do not open packages of paper until necessary so that the paper does not absorb too much moisture from the air. If printing onto envelopes, change your printing layout to avoid printing over areas that have overlapping seams on the reverse side. Use the copier in proper operating environment. Try copying or printing with a different batch of paper. Do not open packages of paper until necessary so that the paper does not absorb too much moisture from the air. Clean the drum. Double printing (previous image overlaps with current image) Thick paper is used. The paper may be too dry. Back of The transfer roller may be printout dirty dirty. Low resolution print feature is activated.*1 There may be too many applications open. Resolution is set to 600 dpi. Faded graphics Toner may be unevenly distributed. Toner is low. Feed thick paper one sheet at a time. Try copying or printing with a different batch of paper. Copy or print a few blank pages to clean the transfer roller. Close all unnecessary applications before printing. Set resolution to 300 dpi. Remove the TD cartridge and gently shake it horizontally to evenly distribute toner. TD cartridge must be replaced soon. Obtain a new TD cartridge.

In this case, the printer driver activates the low resolution printing feature which automatically lowers the resolution of a complex page. 39
