To Users of the Wireless File Transmitter WFT-E7D
Thank you for using Canon products.
The exterior rubber part on some Wireless File Transmitter WFT-E7D unit may change color (turn white) after a short period of time. Customer support for this phenomenon is described below.
We take pride in the quality and performance of our products, and we offer our most sincere apologies to customers using this product who have been inconvenienced by this issue. We hope our efforts will earn your understanding.
Phenomenon
The rubber on the top surface of some WFT-E7D units produced in certain lots from 9 April through 13 July may turn white after a short period of time. We have determined after inquiry with the rubber manufacturer and analysis, that the white substance is zinc bis (N,N’-dimethyldithiocarbamate).
Zinc bis is not used in the production of this product. However, the quantity of rubber accelerator used in the affected production lots was slightly higher than usual. As a result the rubber surface may turn white due to a chemical reaction with the rubber accelerator and other substances. High temperature and high humidity may contribute to this condition. Zinc bis (N,N’-dimethyldithiocarbamate), which becomes deposited on the rubber surface, is created as a result of this chemical reaction.
Affected Product
Only certain WFT-E7D wireless file transmitter units (overseas product name: WFT-E7 A/B/C/D/E) produced between 9 April and 13 July 2012 are affected.
If the first two digits of the serial number are “03” through “06” and the fifth digit is “1”, the unit is affected.
03 xx 1 xxxxx, 04 xx 1 xxxxx, 05 xx 1 xxxxx, 06 xx 1 xxxxx ([x] represents any optional number. )
There are exempted units with countermeasure rubber replaced, please click here for the list.
Please note that zinc bis (N,N’-dimethyldithiocarbamate) will not become deposited on the surface of units not produced in the designated production lots.
Market Support
The rubber part of the affected wireless file transmitters will be replaced free of charge at our service center.
We anticipate that our free repair service will start on 17 October 2012.
Caution on Use
The amount of zinc bis detected during our testing was minimal. While Canon has not received any reports of injury or allergic reactions regarding this product, it is possible for zinc bis, in the small amount found in the rubber surface of affected units, to cause allergic reactions*, such as a rash, when it comes in contact with skin of sensitive persons. In addition, if eyes are rubbed after contact with the substance, symptoms such as red eyes may develop.
As a precautionary measure, thoroughly wash your hands with water if they have come in contact with the rubber surface that has turned white. If any medical symptoms develop, please consult your physician immediately.
*Please note that the occurrence of an allergic skin reaction on contact with this substance depends on length and type of contact with the substance, individual health and physical conditions, and individual skin sensitivity. Not everyone will be affected by allergic symptoms.
