Core Responsibilities

Primary Functions

Set up, calibrate and perform changeovers on automatic and semi-automatic folder/inserter equipment according to job specs and work orders, ensuring correct fold patterns, insert placement, and sealing for variable mail pieces and multi-part forms.
Load, align and feed multiple media types (folded sheets, booklets, inserts, envelopes, windows, variable print inserts) and adjust feed systems to maintain consistent document orientation and prevent misfeeds or double-feeds.
Configure and verify machine parameters including speed, fold plate settings, vacuum/air assist settings, pressure rollers and registration to meet production and postage requirements for each job.
Monitor live production runs to maintain target throughput (pieces per hour), detect feed errors, registration drift, and print-to-cut misalignment, and make immediate adjustments to minimize downtime and scrap.
Diagnose and correct common mechanical and electrical issues such as paper jams, misfeeds, belt slippage, sensor faults, clutch/gear problems and intermittent PLC or HMI errors to restore production quickly.
Perform routine preventative maintenance tasks: cleaning feed wheels, replacing wear parts (belts, rollers, guides), lubricating moving parts, and checking sensors to extend equipment life and ensure consistent operation.
Inspect incoming materials (paper stock, envelopes, inserts) for curl, moisture, sizing tolerances and print quality; document and report out-of-spec materials to purchasing or production planning.
Execute quality control checks at defined intervals: verify correct piece counts, sample open-and-verify inserted content for accuracy, check fold quality, verify sealing integrity and maintain production logs and error reports.
Follow postal regulations and client-specific mailing requirements (bundle counts, tabbing/pressure-sensitive labels, IMb placement, address orientation, weight tiers), and prepare documentation required for mail acceptance.
Accurately count, collate, and package completed mail runs, prepare trays, tubs, pallets, and mailing manifests; stage completed jobs for postage metering or carrier pickup and ensure correct labeling for distribution.
Maintain production records, shift logs and machine run reports (including job setup sheets, downtime reasons, quantities produced, and scrap rates) to support tracking, billing and continuous improvement.
Collaborate with print production, data services and bindery to verify job tickets, reconcile variable data requirements, and escalate mismatches between printed output and job specifications.
Support prepress/print partners by confirming fold and trim tolerances, offering feedback on layout issues that cause inserter jams or misfeeds, and participating in job pre-runs and sample validations.
Train and mentor junior operators and temporary staff on safe machine operation, proper changeover techniques, quality checkpoints, and emergency shutdown procedures to maintain team competency.
Enforce and practice safe work habits: utilize lockout/tagout procedures for maintenance, wear required PPE, follow machine guarding rules, and immediately report unsafe conditions or incidents.
Optimize production flow on the line by sequencing jobs for efficient changeovers, minimizing idle time between runs, and communicating schedule adjustments to supervisors and shipping.
Participate in root cause analysis for repeat failures or high scrap incidents; document corrective actions, update standard operating procedures (SOPs) and contribute to process improvement initiatives.
Interface with maintenance/engineering to coordinate repairs requiring specialized tools or replacement parts and log parts usage to help manage spare parts inventory.
Handle variable data and secure documents with confidentiality and care, ensuring integrity of customer-specific personalized inserts, checks, or financial statements.
Operate auxiliary finishing equipment and conveyors (stackers, tapers, tabbers, strappers, sealers), set them up to integrate with inserters, and ensure consistent handoff between systems.
Accurately capture time, production counts, and material usage in the company ERP or production tracking system and communicate any discrepancies to supervisors immediately.
Perform final quality audits on completed mail trays—verify counts, piece integrity, addressing, and ensure mail meets company and postal acceptance standards before release.
Respond to emergency stoppages and expedite recovery while minimizing damage to product, documenting cause and providing recommended preventive actions to reduce recurrence.

Secondary Functions

Support ad-hoc production requests, rush jobs and weekend runs with flexible scheduling and cross-trained operation of related finishing equipment.
Assist inventory control by reporting low-stock consumables (envelopes, labeling supplies, tapes, staples) and helping receive and shelve incoming material.
Participate in continuous improvement projects (5S, Kaizen, Lean initiatives) focused on reducing changeover time, scrap, and unscheduled downtime.
Contribute to safety programs and periodic equipment audits; help implement corrective actions from safety and quality inspections.
Coordinate with postal operations and carriers to prepare postage manifests, handle returns and manage special handling or certified mail processes when required.
Provide feedback to supervisors and process engineers about design changes that would improve machine reliability or throughput for recurring jobs.
Support cross-training efforts by documenting setup recipes and job parameters for insertion and folding jobs in the internal knowledge base.
Perform basic cleaning and housekeeping to maintain a safe, organized and efficient workspace in compliance with facility standards.
Assist in validating software updates or machine firmware changes on test runs prior to full production deployment.
Help validate and implement electronic job tickets and barcode-based workflow controls to streamline setup and reduce manual entry errors.
