Trickle charge will take place when the
switch is in the OFF position or ON (Mains
operation) position
Printer Mechanism
The printer mechanism comprises an eight element, thin film head and DC motor driven transport. Head position is derived from a
home switch and tacho generator, allowing high accuracy printing independent of battery voltage.
Head energy: Internal temperature compensation automatically controls the print pulse width to regulate the energy applied to the
head.
Paper jam: The printer will automatically detect any paper jam which has caused the head to stop moving. If a jam occurs, printing is
aborted and the Status indicator will flash. Turn the printer off, remove the paper jam and turn the printer back on before continuing
printing.
Power Supply
Power is supplied to the printer from a 4.8V internal Nickel-Metal Hydride battery pack or from the external mains adapter. The mains
adapter will trickle charge the batteries when the printer is turned on or off (charge time approx. 16 hours). The Status indicator will
light to show that the battery pack is nearly exhausted.
Power consumption Battery Pack
Standby 30mA Capacity 600mAH
Running -Min 160mA Charge current 50mA
Ave 300mA Weight 100g
Max 700mA Battery life Approx. 2 hours of continuous operation
Note: The peak current can reach a maximum of 3A.
The MCP9800 should only be used in conjunction with an MPS101(UK), MPS102(EURO) or MPS103(US) power adapter. Users
wishing to provide their own power source must contact Martel. The use of an unapproved source may void the printer’s warranty.
Power on Procedure
Check the batteries are sufficiently charged or that the power supply is correctly fitted and operational. Open the paper cup lid and
ensure that the roll is present and that there are no foreign objects inside the paper cup. Close the lid, ensuring that the paper passes
through the paper exit slot. Switch on the printer using the power switch located on the left hand side of the printer. The Power
indicator will light and the printer mechanism will reset
Power Switch Power On Self Test
The self test procedure is initialised by turning on the printer with the
Paper Feed button pressed. Release the Paper Feed button and the
self test procedure will start. This will check most of the printer
functions, except for the serial interface, i.e.

Mode of Operation
Text mode is the default mode of operation for the
printer. In this mode text characters can be printed in
normal, double width, double height, inversed,
reversed, bold, and underlined format. Graphics can
also be printed using the 'Escape K' sequence.
Graphics mode causes all incoming bytes to be
passed directly to the print head, allowing elaborate
graphics patterns to be printed. Printing occurs after
166 bytes have been received or when the paper feed
button is pressed. The least significant bit of received
bytes corresponds to the lowest dot of the print head.
Hex mode causes all incoming characters to be printed
as their hexadecimal value. Printing occurs after eight
characters have been received or when the paper feed
button is pressed.
Diagnostic mode is used to perform various tests on
the printer hardware using a terminal device connected
to the serial port. This mode is only intended for use by
Martel.
