How to I change the receipt message with a Sharp er-a440?

Make sure the print head is moving freely. check for paper stuck in the printer

Here is the manual for the ER-A410 and ER-A420

http://www.cbspos.com/usermanuals/ERA410_ERA420UIB.pdf

it is a PDF file so you will need an Adobe PDF reader to open it.

Your impression bar need to be adjusted out

Check the drawer sensor .

Hi. You do not need an RS232 cable to program the machine. It can be programmed via the keyboard.
Firstly, it would pay to have the battery checked. They use an internal rechargeable battery which should be replaced every four years. If it hasn't been changed, it can leak on the circuit board and damage the machine. If the battery is not holding a charge, it will also lose your programming when the power is turned off. This is part of normal dealer servicing but you can't be sure that the previous owner has had it serviced and checked.

You will need to program department names. This is listed under "programming for departments - alphanumeric characters" in the instruction manual.To change the shop name on the receipt, see the section called "Programming various functions - programming of print messages".Once you have given those two a try, I can point you to any other parts of the manual you will need. Just let me know what else you want to set up.

Please be more specific. Is it the receipt message that you want to change, or do you need to program other areas of the machine?

· MRS-2
Used to clear all memory and keyboard contents.
This reset returns all programming back to defaults. The keyboard
must be entered by hand.
This reset is used if an application needs different keyboard layout
other than that supplied by a normal MRS-1.
Procedure

2) Set the MODE switch to the (SRV¢) position.
3) Plug in the AC cord to the wall outlet.
4) While holding down JOURNAL FEED key and RECEIPT FEED
key, turn to (SRV) position from (SRV¢) position.
