Ink Jet Cancellation
Inkjet spray-on printers were introduced by Canada Post in 1992 to cancel mail processed by Optical Character Readers (OCRs) and more advanced Multiline Optical Character Reader machines (MLOCRs). MLORCs have been installed at centralized mechanized mail processing facilities nation-wide.
MLOCRs are machines that recognize handwritten or printed addresses, print appropriate barcodes onto envelopes, and then use the information in the barcodes to sort mail into stacks. The Winnipeg Plant which opened on June 4, 2010 has six MLOCRs, each capable of sorting 40,000 letters per hour.
Each MLORC machine in operation has been assigned a specific number which has been usually included in the ink-jet cancellation.
The first jet spray cancels consisted of a single line.
