Managed Print Services: The Library seeks to contract with a Proposer to supply fully compatible toner cartridges that deliver output quality comparable to OEM standards. Toners must not produce artifacts (e.g. streaks, spots, blotches) or cause internal spills. High-usage printers in public patron areas must receive priority service, including expedited toner replacement and maintenance. The Proposer is expected to remotely monitor toner levels and print metering and proactively replace toners before depletion to avoid service disruptions. High-capacity toners are preferred. The Proposer must provide a replacement schedule and specify the threshold (e.g., "X days to empty") for initiating replacement. Ideally, toner replacement should be as automated as possible, minimizing Library staff involvement. However, the Library may accept standby toner for manual replacement if it results in cost savings.
