Cleaning and Testing the BJ Cartridge Print Head The print head in the BJ print cartridge contains nozzles through which ink is propelled onto the paper.
  • Page 49: When To Replace The Bj Cartridge

    Chapter 1: General Description copying a document. If necessary, repeat this procedure up to four more times (giving five cleanings in all). If the problem persists after this, install a new BJ cartridge. When to Replace the BJ Cartridge How frequently you need to replace your MultiPASS C5OOO’s BJ cartridge or one of its ink tanks depends on how you use your grayscales, you will need to replace the cartridge more often than if you print mainly text.
  • Page 50 If the mcssagr Cl IANGE CARTRIDGE appears in the LCD display, the BJ cartridge may have run out of ink. This message also appears if the MultiPASS C5000 has to store a fax in its memory because the cartridge is out of ink.
  • Page 51 Once a BJ cartridge is unwrapped, its print head must be kept from drying out, or it can clog and fail to work properly. A cartridge installed in the MultiPASS C5000 is protected from drying out by automatically moving to the home position at the right side of the unit and capping itself.

  • Page 192 Part 2: Printer BUSY When the printer makes BUSY high, it cannot receive data. The BUSY line goes high in response to a -STROBE pulse. This line remains high until the data are read. BUSY is also high under the following conditions: The receive buffer is full of data.
  • Page 193 Chapter 1: General Description Timing chart The parallel interface transfers data in one direction only: from computer to printer. The data path is 8 bits wide. The printer and the computer synchronize data transfer with the interface signals, -STROBE, -ACKNLG, and BUSY. When the computer is ready to send a byte of data to the printer, it puts the byte of data on the data lines (DATA 1 through DATA 8).

  • Page 207 Part 2: Prlnter 2.8 Optimum Printing Direction Control To prevent vertical misalignment of the printed characters, etc., when printing data is printed continuously in the direction of the paper feeding direction, printing is executed with the carriage moving from only one direction. However, when the printing in the paper feeding direction is not continuous, since vertical misalignment is not so noticeable the printing direction is alternated so that printing is also executed from the opposite carriage direction.

However, the facsimile transfers data to the host computer using the four status signal lines by dividing &bit data into 4 bits and sending them.
  • Page 210 Chapter 2: Technical Reference b-2) Data transfer from the facsimile to the host computer In Nibble mode Data is transferred by the following steps. The host computer sets HostBusy to low to indicate that it is ready to receive data (0). The facsimile sets the low-order nibble of the byte (0 to 3 bits) to four lines: nDataAvai1, Xflag, AckDataReq, and PtrBusy.
