The most likely cause for this OFFLINE status on the PC is which interface is selected on the printer. I think the printer defaults to Serial interface, so if you are using USB ensure you select the USB interface via the control panel on the printer, similarly if the connection is parallel ensure the parallel interface is selected. If the connection is serial, ensure the cable is of the correct pin configuration and ensure the serial interface is set up correctly.
The error you are getting "Buffer Overflow" is occuring due to flow control not working on the serial interface.
You need to check the serial interface settings on the pritner, ensure these match the host computer system (Protocol, Baud Rate, Paraty, etc)
Also check your serial cable, ensure the pin configuration is correct.
My guess is the printer is set to Ready/busy and you are running Xon/Xoff, you will need to change this in the printers menu along with the other serial interface settings
To change the settings, make sure you have a good ribbon installed.
Press the MODE button. The SEL light will go out. Menu light will come on.
Press the GROUP button until the printer prints something like:
Serial Interface Parity None
To change the Parity, press SET. A new line will print as:
Serial Interface Parity Odd
Press SET until the Item is the one you want.
Then Press the ITEM button. It will then print:
Serial Interface Serial Data 7 or 8 bits 8
Again if you want to change it, press SET. Otherwise go to the next Item.
Continue using the ITEM button to choose the item you want to review or change and the SET button to change the selection.
When you have made all the changes verify by going through all of the items with the ITEM button. When you are satisfied, Press the MODE button to save all of the changes. (The Menu light will go out.)
I would hazard a guess that the printer is connected via the serial interface.....
If this is the case you either have a problem with you serial interface settings or the serial cable pin configuration does not match the printers serial interface pin configuration..
I would recommend printing a MENU print on the MT661 and check the serial interface settings these NEED TO MATCH THE HOST SYSTEM
To print a menu print.
Put the printer OFFLINE
Press the DOWN ARROW to HELP
A menu print will be printed look for things like Protocol, Baud Rate, Data Bits, Stop Bits etc
These need to be set to match the host computer system.
I am a little confused on what you are trying to do. From what I know, a 4230-101 printer is a Twinax version not a coax. Might you have a 4230-201? That would be a Coax version. Also if you are trying to go from one interface to another and have a lower level machine 1 series or 2 then it’s going to require you to change out a lot of parts. You have a few different options if you need serial. They make a 4232-302 which is a serial/ parallel printer or a 4230-4I3 or 4S3 which is a twinax serial and parallel printer your choice of IPDS or not. If you have any questions or are looking to get out of your 101 printer and into a serial printer I can work something out where I can take yours in exchange for a serial printer fully refurbished. Please give me a call and we can work out the details. Thanks, Rory Cardenas Midrange Repair and Parts 3821 W 127th Place AlsipIL60803 708-597-4222 x240 email@example.com AOL IM: RORYMRP
What connector/interface does your PC has
9-pin or 25-pin connector
If it has 9-pin connector: use the following: DB-9 RS-232 Serial Connection or DB-25 RS-232 Serial Connection
If it has 25-pin connector: use the following: DB-25 Serial Connection or
DB-25 RS-232 Serial Connection
If you are configuring the computer to use an RS-422A serial port, you need a special cable. Contact the computer or printer network manufacturer to see if an RS-422A cable is available. If no cable is available, contact your computer manufacturer for your computer pin assignments and have a cable constructed.
The default configuration for the serial port on the printer is for RS-232C serial communication. To set the printer to use RS-422A serial communication, change the control panel Serial Menu’s SERIAL setting to SERIAL=RS-422.
