H2-0 Fusing unit temperature error
H4-0 The fusing unit doesn't heat up.
You have to reset fuser errors with simulation 14.
SM 5-1 should turn the lamp on. If lamp blinks on and off it is the thermistor, if it does not it is the lamp, but check the contacts on the lamp/fuser -- they have been known to erode.
Also check thermal fuse, if defective replace.

My sharp al-1530cs keeps flashing a L and will not copy

L what? These Sharp machines will flash a letter followed by a number such as L 1. The L1 is the most common so I will give you my link for that solution. If this is not correct just reply back with the code you have.
Good Luck and Thank You for using Fixya.

You should have on the right side of the display panel a "C" key and on the far left side your "light" exposure key.

Press c-exposure-c-exposure the scree should go blank. using your key pad make the display show 24 then press your copy key. then make it show 7 the press your copy key. Press the C or CA key until the copier resets. The light should have gone off.

Sharp AL-800 light copies

Check the machine for a **** or dust glass above the drum.
Check and clean coronas, the wires and shells may be dirty reducing charge.
Run a few white copies, to check of the toner / carrier ratio is low.

Hope this is of some help.

Sharp AL 800 won't copy bottom 2 inches across page. Replaced toner cart and still missing bottom 2 inches across page. What do I try next?

Pretty sure you need to replace the drum cartridge. When the drum blade goes bad or edges of the drum go bad it will cause this issue. You can stop a copy as it is passing thru and compare the edge as it is being transferred to the drum and what is on the paper to see what I am talking about.

I can be more specific if necessary

Blinking letter L

The scanner probably got locked. If you reach up under the scanner in the cavity where the copies come out, there is the locking mechanism. turn it 90 degrees to unlock it. turn the copier off and then back on to clear the code.

Toner error message on copy machine

Is "CH" steady or flashing? If it's steady, the door is not shut properly.
If it's flashing, the machine doesn't detect the presence of the toner cartridge (defective toner cartridge). Try another toner cartridge (an empty cartridge will do).

To get the blue handle to stay locked sometimes takes fiddling with it when the cartridge is in.
