SYSTEM OVERVIEW OF THE 4635 LASER PRINTING SYSTEM
Figure 1-14. 18/36 track cartridge tape drive control panel
The following push buttons are located on the tape drive front
panel:
1. Ready button. Places the drive "online" to communicate
with the system controller. This button also serves as the +
Scroll control for menu selection when the alternate mode is
selected.
2. Rewind button. Rewinds the tape to the Beginning of Tape
(BOT). This button also serves as the - Scroll control for
menu selection when the alternate mode is selected.
3. Unload button. Rewinds tape completely into housing and
then ejects the cartridge. This button only functions when
the tape drive is "offline" to the controller. This button also
serves as the Select function for menu items when the
alternate mode is selected.
4. Reset button. Stops tape motion during rewind, unload, or
"online" operation. If the drive is "online" pressing this
button will take the drive "offline." This button also serves
as the Cancel function, taking the operator back one menu
level when the alternate mode is selected.
5. Mode button. Switches modes of the tape drive, displaying
menu selections and assigning alternate functions to the
buttons described above. This button only functions when
the tape unit is not ready.
The front panel also contains the following three indicator lights:
6. Read only. Is illuminated if the installed cartridge is write
protected.
7. Ready. Is illuminated when a cartridge is loaded and the
tape drive is online to the system controller.
8. Mode. Is illuminated when the alternate mode has been
selected.
Note: If all three indicator lights are flashing, a problem has
occurred and operator intervention is required.
Floppy disk drive
When installed, the optional floppy disk drive is located in the
system controller, to the right of the 1/4 inch cartridge tape
drive. It allows you to transfer files between a floppy disk and
the system controller's hard disk.
