Tip

Sharp AL Series Copier H3 H-3 code reset procedure


To reset the H3 condition on just about any Sharp AL series copier press the following key's in sequence and as quickly as possible (with 4 seconds for the first 4 keys)
Press "C" then the far left key (exposure mode) then the "C" key then the far left again.
So in other words C, far left, C, far left
Some model's use 2 other initial codes, so you may need to use one of these 2 alternate codes to get your display to go blank. The rest of the procedure is the same.
Alternate codes are: #, * , C, * or pound,star,C,star and also
#, Interupt, C, Interupt
If done correctly the display should go blank.
Now key in 14 as if you were going to make 14 copies.
Now press the print button.
The machine should reset and the code should be gone.
9 times out of 10 this is a false code that pops up due to power surges or noise.
If the code comes back this means you have a heater lamp or thermal fuse (more common) failure in the fusing area and will need service.
This works on the following models:
Sharp AL1000, Sharp AL1010, Sharp AL1020, Sharp AL1041, Sharp AL1200, Sharp AL1215, Sharp AL1220, Sharp AL1250, Sharp AL1251, Sharp AL1340, Sharp AL1451, Sharp AL1520, Sharp AL1521, Sharp AL1530CS, Sharp AL1540CS, Sharp AL1551, Sharp AL1551CS, Sharp AL1631, Sharp AL1641CS, Sharp AL1651, Sharp AL1651CS, Sharp AL1655CS, Sharp AL1661, Sharp AL1661CS

Hello sir; that's a simple problem whayever you mention all the parts you replace are not necessary, if you can't reset H4,or H3 then you need to replace "THERMISTOR" that is the device to control the temperature, the parts #RDTCT0128FCZZ.
