Sharp Error Codes
Sharp ram clear (most models with LCD displays)
Press function 9 * 8 # 7 then # or * until display reads memory clear, then press start. Note the other maintenance mode options displayed on the screen when pressing # or *.
Sharp UX-170 maintenance mode: Turn power on, set the line selector at "T" (tone), turn the program switch ON, then press 9 * 8 # 7. Select the next entry from this list: 01 all black copy, 02 ROM/RAM check, 03 auto feeder mode, 04 aging mode, 05 panel check mode, 06 G3 transmission, 07 check pattern, 08 product check (includes diags, 06, 03, 09), 09 signal send mode, 10 memory clear, 11 led array on mode (lamp), 12 product program sw mode, 13 telephone number list printing mode, * soft switch mode, # transmission level. This same procedure works on similar, older models that do not have an LCD display.
Sharp UX-2100 often has power supply problems which cause the unit to lock up.
UX-3200/FO-3250: FO32TD toner/developer costs less than UX30TD and will work in the UX model if 2 fins are broken off so that the unit can be installed in the UX model. Similar duplicity exists with many Sharp laser supplies.
Sharp FO-4800: fuzzy print often results from a bad Motor PWB (polygon mirror) #RMOTN0020GCZZ located in the optical unit.

My sharp AL 1551 CS is getting a L1 error code before that it was getting a E7 code. The scanner will light up and shut right back down, then it shuts itself down again.

Sharp AL 1551cs reading L

I also have an AL-1551CS copier...normally the "L" has something to do with the scanner lock device underneath the left side of the top part (ie; the scanner) It's clear colored and round with protrusion to turn it from locked to unlocked...this is for moving the copier so the scanner (lamp and mirror assm) won't be disturbed. Use a flashlight or such to inspect the position of said device (ie; locked or unlocked) insure it is unlocked.....power back on and tell me if there is a number following the "L" Tim

H 4 error

If the Reset does not work, then you have a fuser error and your machine will need service.
H4 is a fuser heating error code.
Meaning the machine is not warming up because of a bad lamp, thermal fuse, thermostat, and or thermister.
Hope this helps.
Good luck.

H4 error code

H4 is a Fuser Unit heating problem.
This reset is for another model sharp, see if it will work for you.

Press "Clear", "Auto Exposuer", "Clear", "Auto Exposure", the display will go dead... then press "14" (Like your going to make 14 copies), then press "Start".

Hope this works.
Good luck,
