Rev. A Notices for Replacement of the TM-U210/TM-U220/TM-U300 6-13
TM-U220II Technical Reference Guide
Note:
Data may be lost if the receive buffer of TM-U300 is at buffer full state when there is no FIFO
setting, or the FIFO setting is larger than 10 bytes.
However, the TM-U220II has enough remaining receive buffer space to prevent data loss at
buffer full state when DIP SW1-2 is off.
The “Number of bytes from buffer full to release full state” is larger than the TM-U300.
However, you should pay attention to the following.
6.2.4.1 Effect on the application when buffer full condition is changed
The time from buffer empty to buffer full is longer. However, there should be no problems as
the host PC never monitors the time.
6.2.4.2 Effect on the application in buffer full release status
The time from buffer full to release full is longer than the TM-U300. This may cause a timeout to
occur depending on application configuration.
6.2.5 Accessories compatibility
The TM-U220II can use the same consumables as the TM-U300. However, the power supply
units are not compatible. This is explained in the next section.
6.2.5.1 Power supply unit
The power supply unit of the TM-U300 (PA-#### or PB-####) cannot be used for the TM-U220II.
Power supply units that can be used for the TM-U220II are indicated in the following table.
CAUTION:
Do not use the PA-#### or PB-#### power supply units for the TM-U220II. Connection to
an improper power source may cause fire or shock.
6.2.5.2 Consumables
The TM-U220II can use the same consumables as the TM-U300 except for carbon roll paper
(original + two copies). The TM-U220II cannot print on two copies using carbon paper.
6.2.6 Provided statuses and detectors
The TM-U220II has the same statuses as the TM-U300 and new statuses have also been added.
The following section describes them.
TM-U220II (Type A, B, and D)
AC adapter C1, PS-180, or PS-190
Consumables TM-U300 (Type A, B, C, and D) TM-U220II (Type A, B, and D)
Ribbon cassette ERC-38 (B/R) ERC-38 (B) and (B/R)
