Question about HP LaserJet 4730mfp All-In-One Printer
I have an hp laserjet 4345 mfp photocopy machine but it cannot copy anything because the startup button has a red light
The red light on the startup-button indicates that the machine is not ready for a photocopy. Usally there is something stuck in automated document feeder (ADF). Take a close look and see if can see something in the paperpath. If no luck, try pushing a A4 sheet manually through the ADF and see if something comes out with the sheet. Usally there is a small piece of paper, a paper clip or a staple stuck in the ADF. If nothing found in the ADF, the Scanner Controller Board is probably broke, and needs to be replaced. Good luck.

Open the ADF, the top of the scanner/copier.
The ADF glass is the thin strip of glass on the left. Damp cloth with windex or any glass cleaner. Scrub the strip of glass.

a 49.xxxx error on an HP means that there is an issue with one or more hard disks. you can try to re-initialise the hard disk(s) by rebooting the printer while holding the green button. when the three leds are lit, release the green button, and navigate using the numerical buttons until you see "initialise hard disks" on the display of the printer. confirm by pressing the green button again. if all goes well, your printer will take two minutes longer than usual to boot. if you still get the same error afterwards, you need to replace the disk.

SOURCE: error code 13.20.00 for hp
According to HP service manuals, the error you described is in the category:
JAM INSIDE TOP COVER AREA
and more specific:
The pre-feed sensor, the top-of-page sensor, or the fuser-delivery
Those are the points where some paper pieces or even dust can be stuck.
Hope it helped,
