MAI is selling these printers in place of the PT-4225 & 4226 (customized versions of the ML320 & 321) which are no longer available. Differences - Revision C ML320 & 321's with Epson/IBM emulation are nearly identical to the MAI PT-4225 & 4226 except for the following: Cabinet Color - The PT-4225 & 26 have light gray covers. The Okidata ML320 & 321 have light putty covers. Firmware - The PT-4225 & 26 have MAI custom firmware (PROM Q13 on the LXMC-3 main control PCBA and PROM Q8 on the LXHI serial RS-232 PCBA). RS-232 PCBA - PT-4225 & 26's were sold with a serial RS-232 LXHI PCBA with a custom MAI Q8 PROM installed. This serial PCBA is an option on ML320 & 321's and does not have a Q8 PROM. NOTE: Jumper SP1 must be set to position B on 320 & 321's and set to position A on PT-4225 & 4226's. Character Set - PT-4225 & 4226's have a resident MBF International Extended Character Set, as well as, the IBM Char I & II. The Oki ML320 & 321 have an IBM Character Set I & II and Epson character set. Revision Level - Only Rev C ML320 & 321's (identified by the 4th digit in the serial number) share the same parts as PT-4225 & 26's (also Rev C), cover color and firmware are the only differences. Use the MAI PT- 4225/4226 Maintenance Manual for service and spare parts. NOTE: ML320 & 321 Revision A & B printers use different PCBA's. Okidata Printer Part Numbers - Use Okidata P/N 62406101 for the ML320 and use Oki P/N 62406301 for the ML321. These part numbers represent the entire printer unit with EI (Epson & IBM PPR) emulation. Printer Emulation - ML320 & 321's must have the EI (Epson & IBM PPR) emulation firmware for MAI System platform support. NOTE: ML320 & 321's are also sold with Okidata Microline emulation. The Microline emulation uses escape sequences not supported by MAI. Verifying Epson/IBM Firmware - Pressing the LF button while powering the printer On produces a print style test pattern with the first line listing model and firmware information. Example: ML320 (model number) followed by EI (Epson/IBM emulation) or OKI (Oki Microline emulation). Make sure EI is printed, indicating firmware supporting Epson & IBM Proprinter compatible emulation. MAI System Platform Support - Oki ML320 & 321's with EI emulation and with the optional serial RS-232 PCBA installed can be substituted in place of the PT-4225 & 4226. The only exception is that the MBF International Extended Character Set will not be supported (the MBF International Extended Set was primarily used in Europe). Options & Ribbons - PT-4225 & 4226 Pull Tractor and Cut Sheet Feeder options, as well as ribbon cartridges are all compatible to the Okidata ML320 & 321 printers. Printer Device Files - Use the PT-4225 PDF for the ML320 printer and PT- 4226 PDF for the ML321. The printers must have their Setup Menu configured with IBM PPR emulation selected. ML320/321 Recommended Printer Configuration for MAI System Platforms Enter Menu Mode and press the Print button to have the printer print its current configuration settings.

RAMUNNI PRINTER-OKIDATA-ML320,321---------------------------FIB001 Pg002 FIB 00002 MAI COMPANY CONFIDENTIAL 05/13/94 *** INCORRECT FIRMWARE IN 25 PRINTERS SENT TO FIELD *** Subject: Okidata ML321 Printers with Microline Compatible Emulation Instead of Epson/IBM Emulation We have recently discovered that 25 Okidata ML 321 (136 Column 9 Wire Print- head) printers were sent to MAI Systems with the incorrect firmware and Ref- erence Manuals. Externally the printers look identical, but since they have Okidata Microline emulation firmware instead of the MAI standard Epson/IBM Proprinter Firmware, they will print unpredictably when using the usually sup- ported MAI Printer Device Files or Printers Drivers. There are a few ways of determining which models of ML321 printers have the incorrect firmware: 1) On the original Okidata shipping carton the Supplier Part Number will be 62406201 and the Description will be ML321 ML COMP 120V. The correct Epson/ IBM emulation printer will be Part Number 62406301 and the Description will be ML321 EI COMP 120V. 2) If the printers are already installed, look on the left side of the printer for a small silver label with the words MICROLINE COMPATIBLE on it. The correct Epson/IBM printer has no label. 3) If the printer is installed perform the printer self-tests as follows: Make sure the printer has paper installed in front of the printhead, as well as a ribbon cartridge. Power Off the printer. While pressing and holding the LINE FEED button, power the printer ON. Once the printer begins printing, release the LINE FEED button. After a few lines have printed Press the MODE button to stop printing. Printers with incorrect Microline emulation Firmware will have the following information printed on the first line: ML321 OKI A F/W 05.01 YR4077-7026 Printers with the correct Epson/IBM emulation Firmware installed will print the following first line: ML321 EI A F/W 05.00 YR4077-7028 Q13 PROM Change When it has been determined that the printer has the incorrect Microline Emu- lation Firmware installed contact Product Support to obtain Okidata Part Number PROM 31058305 with E/I emulation. This 28 pin PROM replaces the existing Micro- line emulation PROM at location Q13 on the LXMC-3 Logic PCBA located on the inside left side of the printer. The LXMC-3 PCBA may have a 28 pin IC socket or a 32 pin socket. For 32 pin sockets install the new PROM on the bottom posi- tion of the socket exposing the top 4 unused pin positions of the socket. After the E/I PROM has been installed and the printer cover replaced the MICRO- LINE COMPATIBLE label at the left side of the printer should be removed and the printer should be configured for IBM PPR emulation. The recommended printer configuration settings are shown on page 2 of this bulletin. Reference Manual Change Printers with the Microline emulation were packaged with the Okidata Microline 320/321 Standard Reference Guide Oki P/N 59231404. After the conversion to Epson/IBM Firmware some customers may require the Okidata Microline 320/321 Epson/IBM Compatible Reference Guide Oki P/N 59230902. These manuals are available but presently in limited supply. The main difference in the manuals pertains to Escape Code descriptions for printer attributes. References to control panel operation, ribbon cartridge and paper installation, self-tests, option installation and printer menu configuration settings are the same. The Okidata Setup Guide, also packaged with the printer, is the same for both emula- tion printers and should not be replaced.

This update is for MAI Systems Corporation Field Service Personnel use only and contains cross reference to MAI Systems Corporation MM Part Numbers and additional reference numbers not available in the Okidata ML320/321 Maintenance Manual. Printer Revision Level - Rev 'C' printers can be identified by the fourth digit in the printers serial number found on the printer ID label located on the rear Main Chassis Assembly of the printer. This parts breakdown pertains to the standard Okidata 320 and 321 printers in Okidata putty colored covers and NOT the MAI PT-4225/4226 in the light grey covers. Serial I/F - The serial RS-232 I/F (LXHI) PCBA is an Option on Okidata ML320/321 printers. If the serial option is installed, no Q8 PROM will be present and jumper SP1 must be set to position 'B'. Firmware - Okidata ML320/321 printers use different firmware than the MAI PT-4225/4226 printers. The PROMs described below represent the latest revision level firmware (5.00) available for the Rev 'C' printers. This firmware is the EI(Epson/IBM) emulation firmware for the 320/321 printers. Okidata also offers the ML320/321 with Okidata Microline emulation firmware (Microline emulation uses escape codes completely different than those used by the EI emulation printer). The Epson/IBM firmware is very similar to the firmware used on the PT-4225/4226 printers and is the only emulation supported on MAI Host Systems. ML320 - Q13 PROM (MM399393) on Main LXMC-3 PCBA should have P/N 77-7024 or 31058206 printed on it. ML321 - Q13 PROM (MM399394) on Main LXMC-3 PCBA should have P/N 77-7028 or 31058305 printed on it. SELF TEST - Holding down the Line Feed Switch while powering the printer ON will enable a print style test. The first line of the printout lists; printer model number, printer emulation, firmware revision level and part number.
