Safe Mode; When Should Safe Mode Be Enabled - Lexmark MS71x Study Manual

Lexmark MS71x/MS81x & MX71x/MX81x Product Study Guide

Safe Mode

Safe Mode is a new and configurable state in the device that allows print operations to be used even if a
non-critical subsystem failure occurs. When configured in Safe Mode, the device operates in a
minimal/base function state for print operations, permitting a customer to continue printing until service
can be arranged to repair the device.
Warning! Safe Mode is intended as a short‑term workaround and should only be used when a
critical print job must be completed before service can be arranged to repair the printer. In most
customer situations, it would NOT be appropriate to enable this mode. See the table below called When
Should Safe Mode be Enabled? for examples.
Warning! The printer must be returned to standard operating mode before diagnostics can be run or
full‑function printing can continue. This is IMPORTANT! If a customer reports problems with no duplex
capability and/or the inability to select optional input trays, etc., check to see if Safe Mode is enabled – a
warning message will display on the Control Panel.
When Safe Mode is enabled, print jobs are processed based on the product-specific behavior of the
print engine as defined for that mode of operation. Certain service failures and other errors are
suppressed when the device is in this mode so the device is left in a temporary usable state.
When Safe Mode is disabled, if any service failure or other error occurs, the device will follow existing
messaging behavior and the print operation will be terminated. The device may also shut down due to
certain failures based on existing definitions.

Hypothetical Customer Situation
Customer has a deadline to complete an
important print job before the end of the
day – Service cannot be dispatched until
tomorrow.
Customer needs to complete a print job
to send to a publisher by the end of the
day. They only have 5 more pages left to
print from the job. Service will not be out
until tomorrow.
The customer is printing PowerPoint
handouts for a meeting next week. They
only had a few pages left to print.
Enable Safe Mode? – Why/Why Not?
YES. The customer has a critical need to
continue printing. Safe Mode will disable the
duplex and allow the customer to continue to
print at reduced functionality.
NO. The customer has a critical need to
continue printing; however, Safe Mode will not
disable Tray 1. For this printer, Safe Mode
ignores all Input Options: Tray 2, Tray 3, etc. but
Tray 1 functionality remains enabled.
NO. The customer does not have a critical
need to continue printing.
