My printer/scanner worked fine, but we had a power outage (it's plugged into a surge protector) and now it won't work. It keeps flashing the number "4" and then the letter "H." I understand there's a series of buttons to hit to reset it, but I don't know what they are for my particular model. Any help would be greatly appreciated!!!!

To reset the H4 condition on Sharp AL series copiers 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. WheatlandServices
Scanner movement failure. The scanner is the part under the glass that lights up and moves back and forth. So if you lift up the feeder so you can see the glass, turn the machine off for a few seconds then back on. Watch the movement of the scanner. It should move right and inch or two then back to the left. If all goes well the copier should come to ready. Lay a piece of paper on the glass and press the print button to watch the scanner movement. If it binds up or does not scan correctly there are 2 possibilities.
1) your scanner lock is engaged and is preventing the scanner from moving. Check the clear plastic dial located under the far left upper side of the copier, near where the paper exits the machine. Make sure it is in the unlocked position.
2) Your scanner rail is dirty and dry. This rail can be seen under the glass towards the back of the copier. The scanner rides on this rail. It is very common for these to get dirty and for the grease to dry up causing the scanner to freeze up on the rail. The glass must be removed and the rail cleaned and lubricated.
Good Luck and thank you for using Fixya.
instead of a screw, some models have a dial to lock the scanner for moving machine. look above where the paper exits machine twords the left side under the scanner assembly for a dial switch and turn it.
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
I had to add a printer manually after going through the driver installation process. Add printer,next,local printer (do not check plug and play),next,create new tcp/ip port, next, type in the printer ip address, next, I used the Generic network card here and it worked fine for me. You can figure it out from here
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.
