(2) Put mechanism lock lever inside of main body, pull down printer mechanism.
When paper remains inside of printer, remove this paper.
(3) Removing paper jam
Remove paper jam manually with care. To pull out the paper from printer mechanism,
pull it out carefully at head up condition.
(4) Canceling cutter lock
Remove paper inside of paper cutter and turn ON power. In case cutter blades to home position and
carries out initializing, cutter lock was cleared completely.
In case cutter does not return to home position or occurs some error again, turn OFF power,
turn the knob which locates on left bottom side of auto cutter to the front side as shown in the below,
then return cutter blade manually and remove the paper inside of auto cutter.
(5) After fixing the problem, pull down head up lever and return printer mechanism to its home position.
Cautions :
Since print head and motor are hot, do not carry out this action right after printing.
This may cause burning from this heat.
For removing the remaining paper, do not touch the surface of print head and motor.

3.8Self print function
By supplying power as pushing FEED switch or send RESET signal to this printer,
type of characters which is used, ROM version and DIP switch setting etc are automatically printed.
For CBM-291, paper is automatically cut off after this self printing.
3.9PE and Mechanical alarm
3.9.1 Paper end (PE)
This sensor detects the existence of paper. Printer stops printing when roll paper runs out, outputs BUSY and
PE signal and lights up PAPER lamp. When new roll paper is set, this signal is canceled and PAPER lamp
lights off. And then, printer starts printing and becomes data waiting status. When any print data is remaining
in print buffer, make sure that printer starts printing the data after new roll paper is set.
3.9.2 Mechanical alarm
This printer stops printing, stops supplying motor and print head with power and outputs BUSY signal and
FAULT (in Parallel interface) signal to host computer, when the motor of printer mechanism is locked, auto
paper cutter is locked, or temperature of print head is getting high. In this case, turn OFF power supply and
clear the problem. To make printer stand-by mode, turn ON power supply after clearing the problem.
Make sure that the data which is stored in the buffer is to be cleared due to power supply is turned OFF.
Absolutely, do not carry out clearing the problem during power is ON.
• Auto paper cutter lock, paper jam.
Turn OFF power supply and clear the problem. To make printer ready for print, turn ON power again after
clearing the problem. In this case, the print data which is remaining inside of print buffer is cleared due to
power supply is turned OFF. Absolutely, do not carry out clearing problem supplying power.
• Head-up condition
Pull down had up lever forward. Print head is pulled down and error signal is cleared, then printer
becomes ready for print.
• Heating up of print head temperature
When temperature of print head is getting high due to continuous printing etc., printer stops printing.
During temperature of print head is high, any operation is not available, keep printer without printing.
As soon as temperature of print head goes low, error signal is canceled automatically and printer
becomesready for print.

CBM-290/291 User’s Manual
In 1/2 bit from the mark-to-space starting edge, state is read once again. When "space" state is confirmed,
it is recognized as the start bit. If it is "mark" state, it is not taken as the start bit. Without taking it as an
error, detection of a start bit is carried out once again.
(2) Data Bit + Parity Bit
Data bit and parity bit are sampled at 1/2 start bit for time length equal to 1 bit. The state thus sampled is
taken as the data for the bit concerned. Bits are named as Bit 0, Bit 1, ..... parity bit counted from the one
close to the start bit.
(3) Stop Bit
The stop bit is a mark level of 1 bit or more. With "space" having been detected on detection of a stop bit,
framing error takes place.
7.4Error detection
Parity, framing, and overrun are detected. On detection of any error, the data are stored in the buffer as "?".
(1) Framing Error
With "space" state having been detected on detection of a stop bit, error takes place. The data are stored in
