Sharp Copier Troubleshootingby Kyle McBride
During the course of use, Sharp copy machines will occasionally need attention. If you're able to effectively troubleshoot malfunctions when they occur, you will reduce copier down time and keep the office productive.
Machine Does Not Operate
If the start key indicator is off and the machine is not exhibiting any sign of power, check the power cord. Be certain the plug is fully inserted into the wall outlet, and depending on the model, be certain the cord is fully inserted into the back of the copier. Also check the circuit breaker for the electrical circuit the machine is on to be certain it hasn't tripped. If the machine exhibits having power (you can faintly hear fans running, for example), it may be warming up. Wait approximately a minute and a half for the machine to warm up (some large models may take five or six minutes) before concluding that there is a problem.
Paper jams can be caused by a variety of issues in the copy machine, but jamming can commonly be caused by improperly loaded paper in the trays or dirty paper feed rollers. If you get repeated paper jams, remove the paper from the trays and inspect the stack. Look for folded corners, especially on the bottom of the stack. Fan the paper thoroughly and then reload the stack into the tray. Check the paper guides to ensure they are not too tight or too loose. Both conditions can cause paper jams. If you can see the paper transport rollers by opening the ordinary access covers and panels inside the machine, cleaning them might help reduce paper jams. Shut the machine off and unplug it, then take a soft, lint-free cloth dampened with water and wipe those rollers off. A buildup of toner and paper dust can cause them to slip while transporting the paper.
Some error codes can be cleared by removing the paper jam--if one occurred coincidentally with the code--and then rebooting the machine. When an error code occurs, make a note of the code and then follow the instructions on the control panel for clearing it. If the code reoccurs, a service call to a certified Sharp repair facility may be necessary to correct the problem.
For just about any copy quality issue, check your originals first. Be certain that your originals are as good a quality as you want on the copies. The copier can make minor adjustments to improve your copies, but for strong copy quality issues, the machine is going to copy what it sees. Make sure the platen glass is clean to avoid spots and lines on your copies. Lift the platen cover, then take a soft, lint free cloth dampened with water to wipe the glass. Depending on your copier model, you might have two pieces of glass under the platen cover--a large sheet of glass and also a long, narrow strip of glass adjacent to it. Clean both of these and dry them with a soft, dry, lint free cloth. Other common copy quality problems are outputted pages that are too light or too dark. Adjust the exposure settings on the control panel to darken or lighten the outputted image to your satisfaction.
