Original sentence: As of summer 2007 Indigo discontinued the sale of new Series 1 commercial presses.HP will be introducing the upcoming Series 3 engine at Drupa 2008.The Series 2 printing engine can be easily differentiated from the original format by the double sized PIP (dynamic plate), which allows the press to run twice as fast, and many other improvements, prime amongst them, the substitution of the developer drum and associated image improvement mechanisms with one unit, the BID (Binary Ink Developer), which is easily replaceable by the operator should problems arise.The first model to be introduced will be the HP Indigo 7000 Digital Press (Commercial).There are several versions of the HP Indigo Press, which can be broadly grouped by the Printing Engine (Series 1, 2 or 3) and by application - either Commercial (sheet-fed, mainly for paper printing), or Industrial (web-fed, labeling and packaging)
Edited sentence: Series 2 presses are typically operated and maintained with contract service and must amortize both higher initial and maintenance costs in their operation in that regard.The Series 1 presses include less proprietary parts & logic than the Series 2 presses and can be self-maintained without the benefit of contract service.The Series 1 printing engines represent the most mature design in the Indigo line-up but also inherently require operators with more training than with the Series 2 presses.The Series 2 printing engine can be easily differentiated from the original format by the double sized PIP (dynamic plate), which allows the press to run twice as fast.There are several versions of the HP Indigo Press, which can be broadly grouped by the Printing Engine (Series 1 or 2) and by application - either Commercial (sheet-fed, mainly for paper printing), or Industrial (web-fed, labeling and packaging)
