Penggantian filter DM: kapan harus diganti

Filter adalah komponen termurah pada coder CIJ dan yang paling mudah ditunda sampai printhead yang menagih ongkosnya.

Pada coder DM, jalur tinta melewati beberapa filter kecil yang menahan pigmen, tinta kering, dan kotoran sebelum mencapai nozzle. Saat mulai tersumbat, tidak ada yang memberi tahu. Mesin tetap mencetak, tekanan naik perlahan, dan gejala jelas pertama muncul pada hasil cetak.

Apa yang sebenarnya dilakukan filter

Dua hal: menahan partikel padat agar tidak mencapai nozzle, dan menjaga tekanan sistem dalam rentang yang dibutuhkan jet untuk terpecah menjadi tetesan bersih. Filter yang tersumbat sebagian tidak menghentikan mesin — ia membengkokkan kurva tekanan. Itulah sebabnya masalah ini lama terbaca sebagai isu mutu cetak dan tidak ada yang mencurigai filter.

Gejala yang berarti ganti, bukan bersihkan

Perhatikan tiga hal. Kontras turun pada satu baris sementara level tinta normal. Peringatan tekanan hilang setelah jeda lalu kembali di shift yang sama. Jet butuh waktu lebih lama untuk mulai setelah setiap henti. Salah satu saja menunjuk pada aliran terbatas, bukan pada tinta. Filter yang sudah jenuh pigmen jarang bertahan seminggu setelah dibersihkan — ganti saja.

Interval: baca kondisi Anda sendiri

Buku manual memberi interval sebagai titik awal, bukan jadwal tetap. Pabrik berdebu, suhu lingkungan tinggi, dan shift panjang memendekkan umur filter. Pabrik dengan tinta pigmen tiga shift mengganti jauh lebih sering daripada anjuran manual. Catat tanggal ganti dan jam operasi setiap kali: setelah tiga sampai empat siklus Anda punya interval sendiri yang lebih akurat daripada tabel umum mana pun.

Yang perlu dicek sebelum memesan

Nomor part harus cocok dengan model coder dan keluarga tinta yang dipakai: tinta pigmen dan tinta pewarna tidak memakai spesifikasi filter yang sama. Lalu lihat pemasoknya: rumah filter dan O-ring menyebabkan kebocoran hampir sesering filter yang aus, jadi pesan bersamaan. Untuk platform DM, TOPMARK menyediakan filter dan bahan habis pakai kompatibel di samping rangkaian chip, sehingga satu kiriman cukup.

Rutin penggantian yang bertahan

Isolasi jalur tinta, buang tekanan, lalu ganti filter bersama O-ring sebagai satu pasang. Isi sampai jalur bersih, kemudian cetak kode uji dan periksa kontras, bukan hanya ada tidaknya cetakan. Catat tanggal dan jam operasi di shift yang sama — keputusan penggantian berikutnya bergantung pada baris itu. Dengan begitu filter berhenti menjadi kejutan dan menjadi lima belas menit yang terencana.
