Maybe when you reassemble the cartridge something goes wrong. Here is instructions for this http://www.uninetimaging.com/downloads/technical/TecArtWebAdded/Sharp_AL1000_OPC.pdf

http://files.sharpusa.com/Downloads/ForHome/HomeOffice/PrintersFaxMachines/Manuals/Archive/cop_man_AL_1215_1530_1540_1551.pdfPG 62 of the manual indicates that you'll need to contact technical support to decode the error 905-568-7140

This is a critical issue which needs constant monitoring of the device and continuous chat / email exchange.

Thus it is advised to please avail paid fixya services for better support and quick solution.

Check the new unit is correctly seated and open and close all covers on the printer until it clears.
The CH Code is for an open cover but maybe to do with the cartridge not being seated correctly.

check to see if a tiny piece of paper is blocking the paper path. also remove paper from the cassette(which pulls out from the front) and try feeding paper from the tray on the right side. Good luck.

The L1 is for a scanner movement failure. The scanner bar that maoves back and forth under the glass is not moving as it should. The E7 is for a scanner lamp reference failure which CAN be caused by the scanner movement failure so I would try and resolve the L1 first. I have a tip posted here at Fixya that resolves the L1 so try that first and it may fix both problems. If not just comment on this and I will try and help you resolve any remaining issues.
Here is the link to the L1 solution:

L1 or L1-00 indicates 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.
Just power off then on the copier to reset.

Tell us what happens when you reset the L1 with the C, Exp. Mode(Far left key), C, Exp. Mode, 14, then Print clearing method. Do this reset procedure then lift up the ADF and watch with scanner move back and forth. It should bump out and in a few times with the lamp lit. Then park back into home position.

Scanning is not possible thru the parallel port. You must use the USB1.1 port in order to use the scanning feature.
The parallel port is only used for printing.
If you hook up the machine with a USB cable you can print and scan using USB. This includes color scanning.
