When i try to feed the paper it shows an error code E

It sounds like there may be an issue with the motor that drives the paper feed mechanism. The hum/buzz that you hear when you turn it on could be the motor trying to start but failing to do so. The tightness of the paper feed could also be related to the motor issue.
The green "E" on the screen likely indicates an error. Without more specific information about the error code, it's difficult to determine the exact issue. However, it's possible that the error code is related to the motor or paper feed issue.
If you're comfortable doing so, you may want to try opening up the machine to see if there are any obvious issues with the motor or paper feed mechanism, such as a loose or broken part. If you're not comfortable doing this or if you're unable to identify the problem, it may be best to take it to a professional for repair.

Hello,
Please check the entire length of the paper feed path from input to output for a small piece of paper that is stuck causing a "Paper Jam".
You are lucky that you can still print manually as this usually shuts a printer down until the jam is found and removed!
Good Luck!

Turn the printer unit ON
2. Pull the power plug from the back side of it
3. wait 1 min
4. Plug unit back in
5. wait 3 full minutes
6. try to print does the error still exist? If yes continue below

Locate one piece of CARD STOCK paper and manually feed it up against the feed assembly and into the feed.Must be CARD STOCK PAPER, regular paper will not work. the idea is too dislodge any pieces of paper that may be broken off inside the rollers, and not visible to the eye. Repeat this process until the error goes away.

If you continue to experience problems, PLEASE RESPOND TO ME

There should be a specific error code for your printer's paper jam problem. You can try click on the link below, this will show you different error codes for paper feed issues and how to resolve them.

error [6000] or light blinking 3 times is mean there is an error occurred in the LF encoder signal.

it is problem your printer can not feed paper properly or problem paper feed sensor please try to resum button press when occard this E3 signal or clean sensor or claugth

E2-2 = No paper (ASF)
E22 = Carriage error
E23 = Paper feed error
E24 = Purge unit error (bagian cleaning head)
E25 = ASF(cam) sensor error
E26 = Internal temperature rise error
E27 = ink absorber full or platen waste ink absorber full > reset dengan toolsnya
E28 = Ink cartridge temperature rise error -
E29 = EEPROM error
which error message exactly your printe show?

The error code 5700 is the sensor error.Replace the sheet
feed unit and then adjust the timing of the paper feed gears.

The error seems to indicate a failed sheet feed, check the paper path to see for any stuck bits of paper, however I have heard that this can also be caused by a flaky sensor in the paper path.....

apparently the best way to deal with this is to turn it upside down and give it a shake.

hope this helps
