Dear Customer,

As you know, Mutoh Europe’s core business is outdoor printing and signmaking.

A very interesting niche market is digital textile printing. Digital printing can play an important role in the

world of textile printing. Thanks to lots of new developments and the technological possibilities of digital

printing, (such as increasing output speeds, inks offering wider colour gamuts, new ink formulations to

provide durable prints, new coating technologies, etc…,) the gap between traditional machinery (e.g. rotary

screen printers) and drop on demand inkjet narrows considerably.

One application possibility in the field of digital textile printing is heat transfer apparel.

Mutoh’s DT-Series Printers are offered in two different models, i.e. 65” (1653 mm) media width and 90”

(2280 mm) media width.

The Mutoh’s DT-Series Printers are specifically suited to print on transfer paper using water-based disperse

dye inks. They incorporates heavy-duty motorized unwinding/winding system for perfect media handling and

tracking, 8 drop on demand micro piezo inkjet heads (360 nozzles per colour channel), pre-heater and dryer

and a variable head height from 1.2 mm to 4.0 mm to neutralise media cockling (maximum media thickness

1.1 mm).

This manual provides you all required information to set-up and start the Mutoh machine.

Happy printing !

Mutoh Europe N.V.

1.5 PERFECT MEDIA HANDLING

The DT-series printer prints on transfer paper with water-based disperse dye inks. An annoying effect of

transfer paper when coming into contact with ink is expansion of the media.

Notes :

The transfer papers with a low g/m², the thinnest, are most sensitive to expanding. This

expansion results in media coming up from the print platform between the different

pressure rollers.

Therefore, the DT-series printer has been specially developed to avoid the media cockling to occur and to

minimize the print heads to touch the media when minimal media cockling occurs.

1.5.1. Measurements to prevent media cockling

Media cockling is prevented to avoid the print heads to touch the media (protect heads and print result) and

to avoid the cockling structure to become apparent in the print result.

1.5.1.1. Unwinder / winder 100

The unwinder / winder 100 system always provides an equal tension on the media when printing.

It is important that the unwinder / winder 100 is perfectly lined out to prevent cockling. To line out the

unwinder / winder 100, please refer to the user’s guide “Handling Roll Media”.

Caution :

• Before installation and alignment of the unwinder / winder 100, please make sure

the printer is placed level!

1.5.1.2. Print environment of transfer paper

Environmental Recommended

working environment

Temperature: 19℃ - 26℃

Humidity: 30% to 60%, without condensation

Notes :

Please note that some inks require a humidity of more than 50%, other inks can be used

at 30% humidity. Please contact your ink supplier for optimum printing conditions.

Mutoh’s DT-Series Printers – Operation Instructions

17

AP-75171, Rev. 1.1, 25/06/04

Caution :

• The size of the recommended media can change at a fixed ratio according to the

temperature changes of the working environment. Before using media, place the

media roll in the working environment for at least 24 hours, to have it match to the

temperature of the working area.

• Printing before the media could accommodate to the printing environment may

cause media jams due to slippage or creases. This also adversely effects the

quality of printing.

1.5.1.3. Pre-heating of the transfer paper

The DT-series printer is equipped with a pre-heater. (Range up to 50°C.)

Caution :

• We recommend you to set the pre-heater temperature at 50°C. This to be sure that

transfer paper is already expanded a little before reaching the pressure rollers.

1.5.1.4. Extra fans

The DT-series printer is equipped with extra fans to keep the transfer paper flat on the print platform.

Caution :

• We recommend you to select “HIGH” in the vacuum menu. Only use “Low” or

“Medium” when using sheet media.

1.5.1.5. Pressure rollers disabler tool

The pressure roller disabler tool allows a pressure roller to be lifted while printing, thus providing the

necessary space for media to expand.

Caution :

• When using roll media, we recommend you to use two pressure rollers disabler

tools on both side of the media, as well as two on 1/3 and two on 2/3 of the media.

• It is not necessary to use pressure rollers disabler tools when using sheet media.

18

AP-75171, Rev. 1.1, 25/06/04

1.5.1.6. Media Retainers (holders)

The media cockling causes the transfer paper edges to curl. Media retainers keep the media edges pushed

down.

Caution :

• When using roll media, we recommend you to always use the media retainers.

Caution :

• When using the media retainers, do not use the cut function.

Notes :

• When using sheet media, media retainers are not necessary used. If used, please

make sure the media is loaded correctly straight. Otherwise, media can slant and

the media retainers could tear the transfer paper.

1.5.2. Measurements to minimize head touching cockling media

In case of media cockling following tools are available to avoid the print heads to touch the media (protect

heads and print result).

1.5.2.1. ETT (patent pending)

The ETT Extra Tension Tool pulls the media in line with the print platform. The tension on the sides is

always bigger than in the middle. As a result possible curls are straightened.

Notes :

• Always make sure that the edges of the media are supported by the edges of the

ETT.

• Only use the middle part of the ETT if media with is larger than 51”.

AP-75171, Rev. 1.1, 25/06/04

1.5.2.2. Head Height

The DT-series printer can be set at the following head heights : 1.2 mm (LOW), 2.2 mm (MIDDLE) and 4 mm

(HIGH).

Caution :

• We recommend you to use the lowest possible head height. This to obtain the best

printing quality.

Caution :

• At all head heights, be sure that the correct media thickness is set!
