The paper, on a single page or multiple page job, will Intermittently stop in the paper exit area with apx. 4" sticking out of the machine. It seems to stop at the same location each time. Remove the paper and power cycle the machine quickly and flashing "E" then "7" will display. I believ the "2" will sometimes follow as well. Wait longer to power cycle and it will go back to normal. Is this the LSU? If so, should I bother to clean it if the print looks ok or just replace it?

Re: Sharp AR-150N error code E7
The E7-02 is a laser unit problem. I do not know the part number for the laser sync motor but you and just replace that instead of the whole laser unit ( alot cheaper). If I can find that part number I will get it to you. Remember , if you do replace the motor, replace in as clean and still air area as possible. If something gets into the area of the laser/motor, it could scratch one of the lens on the laser head and it would be trashed.

E7 codes deal with the optical scanner unit and or the laser unit. It could also be the lamp in the scanner unit. The E7 is the main code. There is a sub code associated with it. To view the sub code hold down the start button. Below is a list of specific codes and their meanings:
E7-02: LSU trouble E7-10: Shading trouble (Black Correction) E7-11: Shading trouble (White Correction) E7-12: Shading Trouble E7-16: Abnormal laser output
If it is a laser (LSU) issue then the LSU may need replacing. If it is a shading error the first step is to remove the platen glass carefully (with the power off because the inverter board). There is a thin white strip on the bottom side of the platen next to the slit glass. Clean this white strip with a soft cloth and a small amout of isopropyl alcohol. Dust on the optics can also cause shading reference errors so gently blow off the mirrors with canned air.
Perform the following key procedure to reset error:
"#" key, Interrupt key, "C" key, Interrupt key
"1" key, "4"key
Start key, "CA" key.
See if unit cycles and comes back up. If not turn off and then back on the main power. If error reappears on site technical service may be required.
