Question about Sharp AL-1642CS Copier
To reset the H4 condition on your Sharp AL1642 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.
Good Luck and Thank You for using Fixya.

The error that is on your disply is the following.
The fusing temperature does not reach 175 degrees celsius within 30 seconds of turning on the power, or the fusing temperature keeps at 140 degrees celsius.
In sequence press the following buttons [clear]-[density select]-[clear]-[desity select] the display will go blank.
With the copy quantity keys input 14 and press the start/print button, the machine will cycle.
If the error returns then the thermistor and themo fuse will have to be rplaced.
I hope this helps you

the fuser unit is not heating up
unplug the copier then plug back in
make sure the fuser area where you clear jams is latched down
close all doors
if this does not work your fuser lamp is burned out or a fuse has blown on the heater roller
You will have to call service
