H5-01 means you have had five consecutive jams, it would suggest there is either something blocking the paper path, or the paper is not being picked up at all.

Try resetting the machine by the following:
Program, *, clear, *

It will then ask for a simulation code, enter 14 and press print, are you sure?, press yes. Clear all, clear all, should reboot the machine and try again.

If it continues to jam, try a different cassette.

you want to note the frequency of the ghost image. the drums are 1.5 inch round and the fuser rollers are a little bigger like 2 inch round and then the y1 trans belt is way bigger like 19 inches and the y2 belt is like 6 inches. If th ghost only happends with one color you could be pretty sure your problem is with that single drum. if it happends in multiple colors look at the other options first.

y2 and fuser you can see when opeing the right side of the machine
y2 is the wider rubber belt that is lower and the fuser is the hot hting at the top with that flip down cover.

y1 belt comes out with 4 blue screws after the front and right side of the machine are open, the toner waste container is out, and you line up the u shaped thing in the middle. turn in the direction indicted untill you see the green stick apear in the back threw the u.

The drums come out after you remove the developer units. with the machine off Open the front cover remove the toner waste container and loosen the two blue captured screws on either side of the plastic piece that covers the drum units. once those screws are loose check to make sure that the primary transfer unit is disengaged. there is a u shaped thing in the middle that needs to line up. if it is not lined up then rotate the blue screw in the direction indicated until it is. flip the whole plastic bar up if it catches in the middle don't force it rotate that screw. if it catches on the sides then just push it harder the sides make a pop noise sometimes before they give. each of the developer units have a flip up cover that gives you access to another blue captured screw. Pull on the cover from the bottom up then loosen the screw and the developer units will pull towards you. after you pull a dv unit the corresponding drum unit comes out by pressing a button down. the drum units are rebuildable in this machine. there are two blue plastic screws in the end holding a bronze bushing, and two silver plastic screws holding a cover on. there is a snap on side cover that will release the grid. and then three blue screws to get the wiper out. in general on sharps it is ok to pull out blue screws, but never ever pull out red screws.

Let me know if you need more hlep.

You need to make sure the machine is in Copy Mode when you hit
# * C *
enter 14, then touch start
execute on the screen
the machine will reboot and the code should go away.

If it persists you may need some maintenance. If you're in Houston give us a shout. Our labor rates are low compared to the other Sharp dealers in Houston.

If your machine is displaying one of these codes let your service provider know. The codes indicates that the respective drum cartridge has reached it's maintenance or replacement interval. The machine will continue to print normally but you may experience copy quality problems on your printed pages. When the service has been performed the service provider will reset the counter and the code will stop being displayed. In some cases, the machine may be set to stop printing when this code is displayed.

Check the fuser assembly and make sure the 2 levers for envelope printing are not engaged. They reduce the pressure between the fuser rollers and then the copies get issues like that. If that doesn't fix the issue Could be the drum or the transfer belt cleaning assembly causing this problem.

Cyan toner problem. It could be defective toner remove it turn copier off and back on and reinstall toner. If that doesn't work try a new toner. Beyond that you will need a Sharp trained technician.
