Relationship between ambient temperature and number of copies

Number of copies Ambient temperature (print mode)

Original + 1 to 2 copies 5° to 40°C (41° to 104°F)

Notes on slip paper

❏ Slip paper should be flat, without curls, wrinkles, or camber,

especially at the paper edges. Otherwise, the paper may become ink stained.

❏ When usin g multiply-ply c arbo n copy paper, it shoul d be flat

and the glue area should be as small as possible.

❏ Glue area should be located at the top or left edge of the slip

paper.

❏ Since TOF and BOF sensors are optical sensors, paper having

holes at the sensor p osi ti ons or tr anslu cent paper sh ould n ot be used normallly. When using these papers, be sure to disable the paper sensors by ESC c 4.

❏ When using slip paper of 80 mm (3.15”) long or less, load the

paper so that it is fed straight.

❏ Use thinner pa pe r (N30 or equ ivalent) betwe en the top an d

bottom sh e ets of multi-ply paper. I f thick paper i s used, the copy capability is lowered.

• This command is available only with a parallel interface and is ignored with a serial interface.

DLE EOT

[Name] Real-time status transmission [Format] ASCII DLE EOT

[Range] 1≤ n ≤ 3, n = 5 [Description] Tra nsmits the selected printer status specified by n in real time,

[Notes] • The printer executes this command upon receiving it.

Hex 10 04 Decimal 16 4

according to the following parameters:

= 1: Transmit printer status

= 2: Transmit o ff-line status

= 3: Transmit error status

= 5: Transmit slip paper status

• When transmitting status, the printer transmits only 1 byte

without co nfirming the condition of the DSR signal.

• With the serial interface model, this command is executed even in

off-line or receive buffer-full state. However, with the parallel interface model, this command is not executed in off-line or receive buffer-full state because the printer is busy and unable to receive this command from the host.

• The status is transmitted whenever the data sequence of

<10>H<04>H<n> (1 ≤ n ≤ 3, n = 5) is received even if it appears as part of another command. For example,

In ESC ✻ d3=<1>H

m n L n

H [d] n L+256

n n

H, d1=<10>H, d2=<04>H,

Commands 5-3

• This command should not be used within the data sequence of

another command that consists of 2 or more bytes. For example,

If you attempt to transmit ESC 3 n to the printer, but DTR (DSR for the host computer) goes to MARK before n is transmitted and then DLE EOT 3 interrupts before n is received, the code <10>H for DLE EOT 3 is processed as the code for ESC 3 <10>H.

• When Auto Status Back (ASB) is enabled using the GS a

command, the stat us tran s mit te d by the DLE EOT command and the ASB status must be differentiated.

•If the n is out of the specified range, the printer ignores this

command.
