This manual describes the disassembly, reassembly, and maintenance procedures of the line
thermal printer CBM1000. It is intended for field maintenance men.

FFFFEEEEAAAATTTTUUUURRRREEEESSSS

The CBM1000 is a compact-siz ed, line t herm al pr int er dev elo ped for a var iety of a pplic atio ns. It
has abundant built- in fea tures, and can be u sed as a data commu nicati on term inal, PO S term inal,
kitchen terminal and for other applications. Prior to usin g the printer, read this manual thor­oughly to understand its conte nt s.

1. Paper drop-in mechanism; when supplying or replacing paper rolls, all you have to do is just
drop a paper roll into the printer and c lose its cover. This will facilitate paper handling and
head cleaning greatly.

2. High speed (100 mm/s), and low-noise thermal printing.

3. Front-side paper ejection method, which allows the printer to be installed and used anywher e
with few restrictions.

4. Hermetic covering structure, which helps prevent any foreign matter or liquid from getting
into the printer.

5. Built-in input buffer.

6. Bar-code printing (Possible using special commands).

7. Page mode, which allows you to lay out pages freely.

8. Registration of user-defined characters and logos into flash memory.

9. Built-in Drawer Kick-Out interface.

10. Auto cutter mechanism provided as a standard unit.

11. Selection possible, as required, from two types: Easy-to-handle, built-in power supply type,
and lightweight flat AC adapter type.

12. Use of 58 mm wide pa per rolls possible by using t he partition supp lied.

For maintenance operations, note the following:
Notes:
(1) Do not disassemble/reassemble or adjust the machine, if it functions properly. Particularly,

do not loosen screws on any component, unless n e cessary.

(2) After completing an inspection and before turning on the power , be sure to check that there is

no abnormality.

(3) During maintenance, be careful not to leave parts or screws unattached or loose inside the

printer.

(4) When handling the thermal head or electronic component, do not use gloves or other aids

which can easily cause static electricity.

(5) When disassembling or reassembling, check wires and cables for any damage. Do not run

them into a narrow space or set t hem in improper positions.

(6) After reassembling, apply lubricant as required.
